• D. A-ii, B- i, C- iv, D- iii

Answer 1

The correct option is B A- iii, B- iv, C- i, D- ii

Endothecium is one of the wall layers surrounding the microsporangium. It is a protective layer and also helps in dehiscence of anther to release the pollen.

Antipodals are three cells located at the chalazal end of a mature embryo sac.
Synergids are the two cells of egg apparatus present at the micropylar end of a mature embryo sac.
Filiform apparatus is the cellular thickening of the synergids. It plays an important role in guiding the pollen tube into the synergid.

Integuments are the protective envelopes of the megasporangium (ovule).
