I gave my students this multiple choice question: Which of these correctly lists Earth's layers in order from the center to the surface?

Only one answer is correct among these 4 choices:
- outer core, inner core, asthenosphere, lithosphere
- asthenosphere, lithosphere, outer core, inner core
- inner core, asthenosphere, lithosphere, outer core
- inner core, outer core, asthenosphere, lithosphere

Could you tell me which one is correct?

inner core, outer core, asthenosphere, lithosphere
