Answer 1

The correct option is A A- 5, B- 4, C- 2, D- 1

The embryo sac or female gametophyte is called as seven celled and eight nucleated. The male gametes in angiosperms are non motile and remain within the pollen tube. The process of fusion of egg and male gamete is called as syngamy or amphimixis or fertilization or fecundation. Tapetum is made up of enlarged wedge shaped cubical cells, which contain one or more nuclei. It is a nourishing tissue.

Thus, the correct answer is option A.
