i think your answer is a. it splits a cell into two new daughter cells. the others don't really make sense to me so i would go with that one.

prophase is the first step in mitosis and will show one huge circle (nucleus) and centrioles - nothing is being done to it. metaphase is the third step and where the chromatids meet in the middle and the centrioles are at opposite ends. anaphase is the fourth step and where the chromatids start to split/separate. telophase is the second to last step where the chromatids start to split along with the centrioles, it looks like there is getting ready to be two different cells. if you follow this, then it should you to answer what it looks like. have a great day and i hope i you! if i did not answer your question or you are confused, let me know and i will you as much as i can.
