13. Option A is correct.
Wind plays a major role in the pollination of gymnosperms.
14. Option D is correct.
Gymnosperms are not always found near water sources.
15. Option A is correct.
Synapomorphy refers to the evolution of a new trait in a lineage after the diversification.
16. Option B is correct.
All angiosperms contain non-motile sperm. So, it is a symplesiomorphic trait among them.
17. Option D is correct.
18. Option C is correct.
