-As we have learnt 

Ficus carica and other Ficus spp. of Moraceae

  • Flowers of Ficus plants are enclosed within the hollow pear-shaped hypanthium inflorescence. 
  • There is a narrow ori­fice for entering the receptacle within which there are three types of flowers male, female and gall.
  • Figs are pollinated by the gall wasp (Blastophaga) which crawls into the receptacle and lays eggs inside the ovules of the ‘gall flowers’ which it can easily reach by its ovipositor because of the shortness of the style.
  • The eggs develop larvae which feed on the ovules and form galls. 
  • After passing the pupa stage, the larvae develop into mature wasps and crawl out of the fig.
  • In so doing they brush against the male flowers near the orifice carrying away pollen on their bodies.
  • These pollen-laden insects then enter fresh figs where they pollinate the long-styled female flowers and lay eggs within the ‘gall flowers’ in their turn.

Hence, the correct answer is option a.
