Answer:
answer is A
Explanation:
Female gametophyte development is in-situ as it is larger and non-motile and stays in the ovule and is fertilised there
Male gametophyte i.e. pollens develop in anthers and are released either at 2- celled(60% angiosperms) or 3-celled(remaining 40%) which germinate on the stigma of compatable flower and then the generative cell divides mitotically into 2 male gametes
so i think answer should be a
