Correct Answer :
B. A III; B IV; C II; D I
Bryophytes are called as the amphibian of the plant kingdom because these plants can live in soil but are dependent on water for sexual reproduction. Gemma is specialised structure in liverworts for asexual reproduction. Monocotyledons and dicotyledons are two groups of angiosperms. Species of Sphagnum, a moss provide peat that have been long been used as a fuel.
