external fertilization and external development external fertilization and internal development internal fertilization and external development internal fertilization and internal development
I gave my students this multiple choice question: Which pair of terms describes the usual location for fertilization and the first stages of development in human reproduction?

Only one answer is correct among these 4 choices:
- external fertilization and external development
- external fertilization and internal development
- internal fertilization and external development
- internal fertilization and internal development

Could you tell me which one is correct?

internal fertilization and internal development
