Bryophytes comprise

Explanation

A.Dominant phase of gametophyte which produces spores: This statement is incorrect for bryophytes. In bryophytes, the dominant phase of the life cycle is the gametophyte, but it produces gametes, not spores. The sporophyte phase is relatively short-lived and dependent on the gametophyte. B. Small sporophyte phase and generally parasitic on gametophyte (Correct Option): This accurately describes bryophytes. Bryophytes have a small sporophyte phase that remains attached to and relies on the gametophyte for nutrition. It's not an independent, free-living phase. C. Sporophyte is of longer duration: This statement is not accurate for bryophytes. As mentioned earlier, the sporophyte phase in bryophytes is relatively short-lived compared to the dominant gametophyte phase. D. Dominant phase of sporophyte which is parasitic: This is not true for bryophytes. The dominant phase in bryophytes is the gametophyte, and the sporophyte is not parasitic but attached to and nutritionally dependent on the gametophyte. Summary: Bryophytes are characterized by a small sporophyte phase, which is generally parasitic on the gametophyte. The gametophyte phase is the dominant and independent phase in the life cycle of bryophytes. This is what distinguishes bryophytes from other plant groups.
