A body sinks in water when

A
density of water is greater than density of body
Correct answer
B
density of water is less than density of body
C
density of water is equal to density of body
D
the body is heavy

Solution

A body sinks in a liquid if the buoyant force acting on it is less than its weight.

This occurs when the density of the body is greater than the density of the liquid.

Therefore, a body sinks in water when the density of water is less than the density of the body.

Answer: density of water is less than density of body

Hence, the correct answer is option: 'B'.
