Answer:
Correct Answer: E
Solution:
The level of water does not change.
The reason is that when drinking the water (say m gm), the mass of the man increases by m gm and hence water displaced by the man increases by m gm, tending to raise the level.
However, this much water has already been consumed by the man.
Therefore the level of the pond remains the same.
