Solution
The correct option is B Homosporous but a few are heterosporous
Most pteridophytes are homosporous (produce spores that are all the same size), while a few groups are heterosporous with large megaspores and small microspores. The megaspores produce megagametophytes, that only form eggs, and microspores only produce microgametophytes, which produces sperm.
Hence the correct option is B.
