D

Text Solution

Verified by Experts

The correct Answer is:
B
The question mainly asks whether the nucleophile will undergo conjugate addition or direct addition,
Nucleophiles that are relatively weak bases such as `CN^(-), RNH_2` and `X^(-)` give conjugate addition, whereas strong bases such as R - Li, R - MgX give direct addition.
