Which of the following is incorrect related to monosporic development (in general)?

A
It results in the formation of an embryo sac that has 7 cells and 8 nuclei.
B
In this type of development, more than one cell of the nucellus differentiates to form many megaspore mother cells to compensate for the loss of 3 megaspores.
C
It involves 3 successive mitotic divisions of the functional megaspore, which initially involve only karyokinesis, and cell walls are laid down later.
D
In this type of development, three of the spores degenerate and only one spore remains functional.

Verified by Experts
The correct answer is:
B

Ovules generally differentiate a single megaspore mother cell (MMC) in the micropylar region of the nucellus. In a majority of flowering plants, one of the megaspores is functional while the other three degenerate. Only the functional megaspore develops into the female gametophyte (embryo sac). This method of embryo sac formation from a single megaspore is termed monosporic development.
