Answer 1

Answer: (B)

An independent sporophyte

Dryopteris is a fern which belongs to Pteridophyta. It has spore-bearing leaves. Funaria is a moss. They lack vascular system. The gametophytic stage alternates with the sporophytic stage. Dryopteris differs from Funaria in having an independent sporophyte. The main plant body is sporophytic (2n) in Dryopteris but is gametophytic in Funaria and sporophyte is dependent on gametophyte in Funaria.

So, the correct answer is option B.
