Answer:

D

Explanation:

The gametophyte of these lower plants produces haploid spores/gametes. These spores/gametes either produce new gametophytes or swim and fuse with another haploid spore/gamete to produce a zygote. The zygote grows into a sporophyte (the other phase of these plants’ life cycle). This is why these plants thrive in moist conditions. Examples are mosses, liverworts, and ferns.
