Answer 1

c

Answer 2

C. is Lamarckian because it says that characteristics acquired during the father's lifetime are passed on to the offspring.

Not A. because insecticide resistance is not acquired by the flies that survived. They just had a lucky variation that allowed them to survive.

Not B. because that's an example of speciation caused by geographic isolation.

Not D. or E. because they include the wrong choices from A. and B.
