Solution
The correct option is D Prothallus
The fully grown sporophyte, what is commonly referred to as the fern, produces genetically unique spores in the sporangia by meiosis. The haploid spores fall from the sporophyte and germinate by mitosis, given the right conditions, into the gametophyte stage, the prothallus. The prothallus develops independently ; it grows sex organs that produce archaegonia and antheridia.So, the correct option is D. (prothallus)
