(C) To determine the hybridization of carbon atoms,we count the number of sigma bonds and lone pairs attached to the carbon atom.In $CH_2=C=CH_2$ (allene),the central carbon atom is bonded to two other carbon atoms via two double bonds.Each double bond consists of one sigma bond and one pi bond.Thus,the central carbon atom forms $2$ sigma bonds and $0$ lone pairs.Since the steric number is $2$,the hybridization is $sp$.
