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