(C) In most angiosperms,the mature embryo sac (female gametophyte) is formed through the process of megasporogenesis followed by three successive mitotic divisions of the functional megaspore.These divisions result in $8$ nuclei.After the divisions,cell walls are laid down,leading to the organization of the typical female gametophyte.It consists of $3$ antipodal cells,$2$ synergids,$1$ egg cell,and $1$ large central cell containing $2$ polar nuclei.Thus,the mature embryo sac is $7$-celled (because the central cell is one cell with two nuclei) and $8$-nucleate.

The female gametophyte of an angiosperm is generally:
