Solution

The correct option is A Two and three
Within the embryo sac, there is a characteristic distribution of cells. At the micropylar end, three cells are grouped together which constitute the egg apparatus. The egg apparatus, in turn, consists of two synergids and one egg cell. The synergids have special cellular thickenings at the micropylar tip. There are three cells at the chalazal end called the antipodals.
So, the answer is A.
