A) Theropod dinosaurs --> birds
B) white peppered moth --> black peppered moth

Explanation / Answer
Answer 1
Option A (descent with modification) is correct.
Parents pass their traits to their offspring , but their offsprings are different from their parents because offsprings are formed as a result of mixing of gametes. Darwin called this as descent with modification.
Answer 2
Option C ( a generic roadside leafy green - -> broccoli, cauliflower and other variety of garden vegetables) is correct.
These varieties of vegetables are developed by human by performing selective breeding.
Answer 3
Option C (they are vestigial) is correct.
Kiwi is flightless bird. Due to disuse of wings they become vestigial.
