Solution

The correct option is A Monosporic, 8 nucleated and 7 celled
The female gametophyte of angiosperms (called the embryo sac) is tiny and contains only a few (typically eight) nuclei; the cytoplasm associated more or less directly with these nuclei is not partitioned by cell walls. One of the several nuclei of the embryo sac serves as the egg in sexual reproduction, uniting with one of the two sperm nuclei delivered by the pollen tube. The most common embryo sac in flowering plant is monosooric, 8 nucleated and 7 celled.
