The correct answer is B. The percentage of crabs with large claws would increase.
Explanation:
Crabs with large claws have more chances to survive and reproduce; this biological advantage will make most of these crabs to successfully reproduce through generations and pass this feature to their offspring. On the opposite, crabs with smaller pincers do not have this reproductive or survival advantage, this implies many crabs with small pincers will not survive a long time or will not reproduce, and therefore this trait will not past to their offspring. Moreover, this situation will cause after many generations the large claws trait prevails, while the small claws trait decreases because crabs with larger claws are more suitable. According to this, it is expected the percentage of crabs with large claws would increase.
