Some redwood trees reproduce both sexually and asexually.

Once a tree reaches maturity, it can reproduce with another tree through pollination and fertilization. The tree then disperses thousands of seeds so that some of them might take root. However, a tree can also reproduce asexually. If it falls down, several smaller trees can sprout from its trunk without the need of fertilization.

Why is it advantageous for a redwood to reproduce sexually when it could reproduce asexually instead?
A. It decreases the time needed to produce B. It increases the genetic diversity of the trees offspring C. It increases the energy needed to produce D. it reduces the time needed to find a mate
