(A) they produce microspores and megaspores.
(B) they produce archegonia and antheridia.
(C) they produce microsporophylls and megasporophylls.
(D) they produce antheridiophores and archegoniophores.​

Answer 1

Answer:

Gymnosperms produce both male and female cones, each making the gametes needed for fertilization; this makes them heterosporous. Megaspores made in cones develop into the female gametophytes inside the ovules of gymnosperms, while pollen grains develop from cones that produce microspores.
