Which of the following accurately pairs the phase of the cell cycle with its primary purpose?

I believe the answer is A. M phase–Cell growth before DNA replication.

According to several sources, mitosis is the cell division that occurs in all cells in the human body, except sperm and egg cells. They produce diploid cells. Meiosis, on the other hand, is responsible for the cell division of the gametes, spermatogenesis (sperm cells) and oogenesis (egg cells), such haploid cells. For instance, your integumentary system, layer of the skin in which your stratum basale always produces new epithelial cells (via mitosis) to take over until the outer layer, called stratum corneum (a continuous replaced dead cells in this layer). 

Ineed the answers so i can you
