An incorrect statement with respect to \[{{S}_{N}}1\] and \[{{S}_{N}}2\] mechanisms for alkyi halide is a strong nucleophile in an aprotic

A)  Solvent increases the rate or favours \[{{S}_{N}}2\] Reaction

B)  Competing reaction for an \[{{S}_{N}}2\] reaction is rearrangement

C)  \[{{S}_{N}}1\] Reactions can be catalysed by some Lewis acids

D)  a weak nucleophile and a protic solvent increases the rate or favours \[{{S}_{N}}1\] reaction.
