Answer 1

The correct option is D Apogamy

Apogamy is a type of reproduction occurring in some ferns, in which the sporophyte develops from the gametophyte without fusion of gametes. Prothallus is a green, photosynthetic, haploid gametophytic stage of fern. It is developed from germination of spore and at maturity gives rise into sexual organs, the antheridia and archegonia.

So, the correct answer is 'Apogamy'
