• A. Gametophyte of fern
• B. Sporophyte of angiosperm
• C. Sporophyte of gymnosperm
• D. Sporophyte of fern

Answer 1

The correct option is A Gametophyte of fern

In Pteridophytes, the spores are released and fall to the ground, where they develop into prothallus. This is the gametophyte stage. The prothallus produces a antheridia andarchegonia. These are exosphoric, flat, green, autotrophic, cordate (heart-shaped), multicellular, short-lived, small reduced, dorsiventral, free living independent and nonvascular.

So, the correct answer is 'Gametophyte of fern'
