Answer:
B. By conducting the male gametes to the female gametes
Explanation:
In plants, the vascular system is involved in the transportation of water and nutrients to different parts of the plant. The xylem is the vascular tissue which carries water from the plant to different parts of the plant. The phloem is the vascular tissue which carries nutrients from the leaves to different parts of the plant. In this manner, the vascular system also provides support to the stem to be kept upright.
However, the vascular system is not involved in conducting male gametes to the female gametes.
