Which of the following is true of conifers? a. female cones produce pollen that fertilizes the egg. b. most coniferous trees have both male and female cones. c. male cones cannot produce pollen unless fertilized by the female cone. d. female cones produce pollen that is trapped by the male cones’ scales.

The correct answer would be option B.

Explanation:

Coniferous trees carry both male and female sporophylls cones on the same mature sporophyte mostly. Conifers are monoecious plants because the bear both male and female cones such as pines. Pines, generating 2 different types of spores: female megaspores and male microspores.

Male cones are smaller in comparison of female cones. Scale present in a male cone contains the pollen that can reach to a female cone to make a egg or seed.

Thus, the correct answer is option b.
