The correct option is C Blastophaga
Hypanthodium is one of the special types of inflorescence. In this type of inflorescence, the receptacle is fleshy and forms a hollow ball-like structure with an apical opening. The inner surface of the receptacle is arranged with three types of flowers. The female flowers are towards the base, male flowers are towards the opening and short-styled sterile female flowers are in between above two. This inflorescence is an adaptation for insect pollination. The inflorescence is pollinated by a gall wasp (Blastophaga). Ficus is an example of this kind of inflorescence. Thus, the correct answer is 'Blastophaga.'
