Why do individuals who are heterozygous for sickle cell anemia have a resistance to malaria? 

A) formation of hemoglobin aggregates makes red blood cells impervious to parasitic infection
B) shortened life span of red blood cells does not allow sufficient time for the parasite to mature in the red blood cell
C) diminished blood flow to the skin as a result of sickled red blood cells blocking capillaries prevents mosquitoes from actually transferring the malaria parasite to individuals
D) sickle cell hemoglobin fibers have both decreased O2 and CO2 carrying capacity;  since CO2 is a mosquito attractant, diminished CO2 exhalation does not attract mosquitoes
E) none of the above
