The correct response is:

had the same likelihood to survive and reproduce as his peers.

This is because in an area without malaria, the carrier of the sickle cell trait typically would not experience the selective advantage that comes with the mutation, which provides some protection against malaria. Therefore, the carrier's survival and reproduction would be similar to that of their peers without the mutation.
