Answer: Option B

Solution(By Examveda Team)

The total concentration of ions in sea water is much higher than that in fresh water because it has large amount of dissolved salts.
Seawater, or salt water, is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of about 3.5%.
Seawater is denser than both fresh water and pure water because the dissolved salts increase the mass by a larger proportion than the volume.
