An agent used against anaerobic bacteria as well as Protozoa is Metronidazole.
Metronidazole is one of the mainstay drugs for the treatment of anaerobic infections. It is approved by the US Food and Drug Administration for the treatment of anaerobic and protozoal infections.
Metronidazole has activity against protozoans like Entamoeba histolytica, Giardia lamblia and Trichomonas vaginalis, for which the drug was first approved as an effective treatment.

The normal life span of sheep is about 10 - 12 years.
Sheep or domestic sheep (Ovis aries) are domesticated, ruminant mammals typically kept as livestock. Domestic sheep are relatively small ruminants, usually with a crimped hair called wool and often with horns forming a lateral spiral.
Domestic sheep on normal pastures begin to slowly decline from four years on, and the life expectancy of a sheep is 10 to 12 years, though some sheep may live as long as 20 years.

Most common method used for animal breeding is Out breeding.
Out-crossing or out-breeding is the technique of crossing between different breeds. It is a useful technique in animal breeding. The outcrossing breeder intends to remove the traits by using new blood.
This is the practice of introducing distantly related genetic material into a breeding line, thereby increasing genetic diversity.

The time temperature combination in plate pasteurization is 72°C for 15 seconds.
Most liquid products were heat treated in a continuous system where heat can be applied using a plate heat exchanger or the direct or indirect use of hot water and steam. The minimum pasteurization conditions are those having bactericidal effects equivalent to heating every particle of the milk to 72°C for 15 seconds.
Modern HTST pasteurization processes must be designed with flow-rate restriction as well as divert valves which ensure that the milk is heated evenly and that no part of the milk is subject to a shorter time or a lower temperature.

Jersy is native of England.
The Jersey is a British breed of small dairy cattle from Jersey, in the British Channel Islands. It descended from cattle stock brought over from the nearby Norman mainland, and was first recorded as a separate breed around 1700.
Jersey adapts well to various climates and environments, and unlike many breeds originating in temperate climates, these cows can tolerate heat very well. The milk is high in butterfat and has a characteristic yellowish tinge.

Humpless cattle belong to the group Bos taurus.

Bos taurus includes European-origin cattle breeds that are characterized by the absence of a hump.

Bos indicus: Refers to zebu cattle, which are humped and are primarily found in tropical regions.

Bos bubalis: Includes domesticated water buffalo, which are unrelated to humpless cattle.

Bos arni: Refers to wild water buffalo and is also unrelated to humpless cattle.

Thus, the correct choice is Option A: Bos taurus, as humpless cattle fall under this group.

Body temperature of cow is 101°F.
Cows are warm-blooded and need to maintain a constant core body temperature. Normal rectal temperature for a cow is around 38°C (101°F).

Rathi is a common breed in Rajasthan.
Rathi is a breed of cattle indigenous to India. It originated in the region of the state of Rajasthan consisting of Bikaner, Ganganagar and Hanumangarh districts. It is an important dual purpose cattle breed of India known for both its milking and draught prowess.
It is well suited for hotter regions of India. Places in Karnataka like Bellary, Gulbarga, Davanagere, sanodoor, and many others places are suitable for this breed.

Buffalo milk is not yellowish because it contains more calcium.
Cow milk is yellowish-white in colour, while buffalo milk is creamy white. In buffalo milk beta- carotene pigment gets converted to colourless Vitamin-A, which makes it less yellowish than cow milk.
Buffalo milk is thicker and contains slightly more vitamins and minerals than cow milk especially calcium is on higher side in buffalo milk.

EDS-76 is Adenovirus.
Egg drop syndrome (EDS)-76 is a viral disease that affects birds, notably chickens, ducks, geese and swans. It is characterized by a sudden drop in production of eggs as well as eggshell quality in apparent healthy laying birds.
It is caused by double stranded-DNA virus, called Duck Atadenovirus A. The diameter of the virus is between 70 and 80 nm by negative staining. The natural hosts of Duck atadenovirus A are wild and/or domestic waterfowl such as ducks and geese.
