The correct is option (B) 50.

One megaspore mother cell (MMC) in an ovule typically goes through meiosis to produce four megaspores. The female gametophyte (embryo sac) is formed by one megaspore, which is still functional, while the other three degenerate and ceases to function.

The female gametophyte (FG) of flowering plants develops from the megaspore mother cell. Only one hypodermal cell out of a group of somatic cells in the ovule primordium changes its cell fate to become the MMC. The MMC then goes through a series of meiosis and mitosis to create the mature FG, which contains seven cells and eight nuclei. Although SPL/NZZ, the essential transcription factor for MMC formation, was discovered many years ago, it has long been unclear which and why only one somatic cell is selected as the MMC.
