(B) In a typical angiosperm,the mature embryo sac (female gametophyte) is $7$-celled and $8$-nucleated. It consists of: $1$. Three antipodal cells at the chalazal end. $2$. Two synergids and one egg cell at the micropylar end (forming the egg apparatus). $3$. One central cell containing two polar nuclei. Thus,there are $7$ cells in total,but because the central cell contains two nuclei,there are $8$ nuclei in total.

Choose the correct option for the embryo sac of angiosperms.
