I gave my students this multiple choice question: Which is an example of asexual reproduction?

Only one answer is correct among these 4 choices:
- one cell divides into two cells
- two cells unite to form one cell
- a gene in a cell mutates
- egg cells are produced

Could you tell me which one is correct?

one cell divides into two cells
