Solution

The correct option is A Spores
Answer is "Spores" i.e. option A
Fern is a diploid plant body. Meiosis leads to formation of cells that contain half the number of chromosome than parental cells. In ferns, these cells are the spores. So a spore is the product of meiosis in ferns.
Gametes, prothallus are formed at later stages of spore germination. Protonemal cells are found only in mosses and not ferns.
Hence, answer is "Spores"
