From one megaspore mother cell number of megaspore finally produced is

Answer: Option C

From one megaspore mother cell number of megaspores finally produced is 4.
Megaspores are a type of spore that is present in heterosporous plants. The megaspore, or large spore, germinates into a female gametophyte, which produces egg cells.
During megasporogenesis, a diploid precursor cell, the megasporocyte or megaspore mother cell, undergoes meiosis to produce initially four haploid cells.
