Acrylonitrile $(CH_2=CH-CN)$ contains an electron with drawing (-CN) group which can stabilize the carbanion intermediate .Since,in anionic polymerisation ,carbanion intermediates are produced,therefore polymerization of acrylonitrile must be carried out under anionic conditions.
Hence (a) is the correct answer.
