In the majority of flowering plants, a certain pattern is followed in megaspore mother cell (MMC) undergoing meiosis and producing megaspores. How many functional megaspores would be produced with 32 MMC?

32

The correct answer is Option (2) → 32 

In most flowering plants (monosporic development), each megaspore mother cell (MMC) undergoes meiosis → 4 megaspores, but only 1 becomes functional and the other 3 degenerate.
So, with 32 MMC → 32 functional megaspores.
