D — geographic isolation.

Different islands separated finch populations so they experienced different environments and selective pressures. With little or no gene flow between islands, natural selection produced different structural and behavioral adaptations (adaptive radiation). Options A and B describe Lamarckian ideas (use/disuse, acquired traits) which are incorrect; reproductive isolation can result from geographic isolation but the primary cause here is geographic separation.
