Answer: Option B
Solution(By Examveda Team)
a. Polytene chromosome with numerous chromosomes - Polytene chromosomes are large chromosomes that have thousands of DNA strands. They provide a high level of function in certain tissues such as the salivary glands of insects.b. Lampbrush chromosome is oocytes - Lampbrush chromosomes (LBCs) are transcriptionally active chromosomes found in the germinal vesicle (GV) of large oocytes of many vertebrate and invertebrate animals.
c. Aerocentric chromosome is centromere near one end - Acrocentric chromosomes are defined as having the centromere near and at the end of the chromosome.
d. Sat chromosome is with a satellite - The satellite at metaphase appears to be attached to the chromosomes by a thread of chromatin. In addition to the centromere, one or more secondary constrictions can be observed in some chromosomes at metaphase. These chromosomes are called satellite chromosomes.
