Best answer
The correct answer is (c) N,N-Dimethylmethanamine

To explain I would say: The compound is a tertiary amine with three methyl substituents. One of the methyl groups is considered as the parent chain with the N atom and the other two acts as substituents. These are represented by N, N- as they are the same groups and are directly attached to the nitrogen atom.
