Answer:
D. The male butterfly deposit sperms into the female butterfly.
Explanation:
A male green-veined white butterfly is able to sense whether a female has already mated or whether she is a virgin. If she has previously mated, he deposits more sperm, producing an ejaculate up to 26% larger than if she were a virgin. This overload of sperm helps ensure that she does not find another mate too quickly.
