Which plant structure is the dominant sporophyte of angiosperms?

A. eggs

B. flower

C. pollen

D. spores

I think the correct answer from the choices listed above is option B. The plant structure that is the dominant sporophyte of angiosperms would be the flower. Sporophyte is the asexual and usually diploid phase, producing spores from which the gametophyte arises and for angiosperms the dominant would be the flower.
