The correct option is
B Cannot flower
The gymnosperms are a group of seed-producing plants that includes conifers, cycads,
Ginkgo, and
Gnetales. The term "gymnosperm" comes from the Greek word meaning "naked seeds", after the unenclosed condition of their seeds (called as ovules in their unfertilized state). Their naked condition stands in contrast to the seeds and ovules of flowering plants (angiosperms), which are enclosed within an ovary. Gymnosperm seeds develop either on the surface of scales or leaves, often modified to form cones, or at the end of short stalks as in
Ginkgo.
Therefore, the correct answer is option B.
