Solution
The correct option is A decreses
Presssure inside a fluid is the weight of fluid overlying a unit area at the concerned depth. So, as the depth increases, the weight of overlying fluid increases and in other words the pressure increases. So, as the sponge is taken to higher depth, it will experience more compression from all sides. Consequently, its volume would decrease.
