Detailed Solution

alpha - hydrogen atoms present in any carbonyl group like aldehyde and ketone are acidic in nature but the anion left after removal of proton is destabilized due more electron donating effect of other alkyl groups attached with carbonyl group. 

Therefore, (A) is true but (R) is false.
