Answer:

The correct answer will be option B (dominant haploid phase in life cycle).

Explanation:

The life cycle of a plant shows alternation of generations in two phases- gametophyte(n) and sporophyte(2n).

Bryophytes is a division of plant kingdom also known as non-vascular plants (mosses, liverworts, hornworts).The gametophyte (haploid) phase dominates in the non-vascular plants while sporophytic phase (diploid) is reduced so, when you see a bryophyte you see a gametophytic stage.

In vascular plants also known as Tracheophytes, the gametophytic phase is highly reduced while sporophytic phase (2n) dominates the life cycle of plants.

thus, the correct answer is option B.
