A Correct answer
Explanation

Sexual reproduction fundamentally requires the fusion of gametes from two parents. This means one male reproductive cell (sperm) must unite with one female reproductive cell (ovum/egg). Options involving two cells of the same sex or multiple cells of both sexes describe processes that don't occur in standard sexual reproduction.
