Q.
$CH_{3}Br\ + \ Nu^{-}\ \rightarrow \ CH_{3} - \ Nu\ + \ Br^{-}$
The decreasing order of the rate of the above reaction with nucleophiles $(Nu^{-})\ A\ to\ D$ is $\lbrack Nu^{-}\ \ = \ (A)PhO^{-},\ (B)AcO^{-},\ (C)HO^{-},\ (D)CH_{3}O^{-}\rbrack$
A) D > C > A < B
B) D > C > B > A
C) A > B > C > D
D) B > D > C > A
Explanation
