• A. Insects
• B. Wind
• C. Water
• D. Birds

Answer 1

Answer: (C)

In bryophytes and pteridophytes, transport of male gametes requires water. The male gametes , produced by reproductive structures called antheridia, are free-swimming sperm cells that need water to transport them to the female gametes, which are enclosed within structures called archegonia. Because of the need for water, bryophytes are especially common in wet habitats such as bogs, streambanks, and in moist forests. However, they are not restricted to these habitats, and some mosses thrive in deserts, above the treeline, and in the Arctic tundra.

Hence the correct option is D.
