Since there is no solute in the hollow part of potato A no osmosis has taken place and water does not gather in the hollowed part of A.

In case of D even after the presence of a solute osmosis does not take place. Boiling this potato has destroyed the cells and thus no semi permeable membre is there for osmosis to take place.
