A

Actinomycin D is an antitumor antibiotic (a chromopeptide produced by Streptomyces)―it is not a monoclonal antibody [Delay-Goyet, 1991, PMID 1659413].  
Therefore option A is false, whereas options B and C correctly reflect the usual pharmacologic classification that actinomycin D is cell-cycle–nonspecific and vinblastine is M-phase (cell-cycle/phase)–specific.
