Answer:
The correct answer is option B, The gametophytes grow directly from the sporophyte
Explanation:
Conifers are gymnosperm which reproduce through the exposed seeds (seeds not included in fruits) found in the cones. The trees or plant on which these conifers grow are called sporophytes. In the sporophyte, the male and female gametes fuse together to form zygote which further develops into a seed. At the right time, these seeds get dispersed into wind and they grow into new plants known as sporophytes.
