Best answer
Correct option is (c) Base

To explain: Some amount of strong acid is produced at each step of alkylation. This acid can protonate the amine, making the electron lone pair of N unavailable for nucleophilic attack and therefore halt the reaction. For this reason, the acid needs to be neutralised and hence, a base is needed during the reaction.
