The statement implies that there was already an existing allele that provided some protection against malaria. Therefore, option C is logically correct as it suggests that the allele already existed and did not come into being as a response to malaria. Option A is incorrect as sickle cell allele primarily provides protection against malaria only in heterozygous individuals. Option B is also incorrect because it suggests that the mutation occurred in response to malaria, which is not established by the given statement.
