Solution

The correct option is B Both A and R are true and R is not the
correct explanation of A
B
The solubility decreases due to the increase in bulkiness as due to this steric hindrance around the carbonyl group increases so the water molecules can not interact with the carbonyl group easily and less tendency of formation of hydrogen bond.
