People who are heterozygous for sickle cell anemia have the “sickle cell trait.” This is a much milder form of the disease. Looking at the image below, what can you infer about having the sickle cell trait and malaria?

A-Having the sickle cell trait in regions where malaria is common carries a higher fitness.

B- It is better to have the sickle cell trait in areas where malaria is uncommon. C- The genotype for the sickle cell trait is manipulated by natural selection.

D- Having the sickle cell trait in regions where malaria is not prevalent carries a higher fitness.
