Answer:
Correct Answer: C
Solution:
The bryophytes have evolved a life cycle which comprises two phases: gametophyte and sporophyte.
The gametophyte (haploid) is concerned with sexual reproduction and constitutes the most conspicuous, nutritionally independent phase in the life cycle.
The sporophyte is dependent partly or wholly on the gametophyte for nutritional purpose.
