The correct answer is B. Sickle cell is a human adaptation that occurred as a result of exposure to malaria.
Explanation: Sickle cell disease is a genetic adaptation that provides some resistance to malaria, which is caused by a parasite transmitted by mosquitoes. This adaptation is an evolutionary response to the prevalence of malaria in certain regions, making it beneficial for individuals who carry the sickle cell trait. The other statements are incorrect as they misrepresent the facts related to malaria and sickle cell.
