Solution

The correct option is A True
Sea water is denser than river water.
Also we know that the upthrust is directly proportional to the density. The more the density, the greater the upthrust.
Thus, the upthrust due to seawater will be greater than that due to river water at the same level.
This shall make the body appear lighter in seawater.
Hence, the given statement is true.
