Reason : The `+I` effect of the three methyl groups in tert-butyl carbanion tends to make it more stable than methyl carbanion.

Options

A. If both (A) and (R ) are correct and (R ) is the correct explanation of (A)
B. If both (A) and (R ) are correct, but (R ) is not the correct explanation of (A)
C. If (A) is correct, but (R ) is incorrect
D. If both (A) and (R ) are incorrect
