I gave my students this multiple choice question: Darwin's theory that animal species can change over time was inspired by his research on which set of islands?

Only one answer is correct among these 4 choices:
- the Philippine Islands
- the Virgin Islands
- the Hawaiian Islands
- the Galapagos Islands

Could you tell me which one is correct?
