Explanation:
Malaria has proved endemic to the human species as it has killed the humans in large numbers and it has acted as one of the strongest selective force.
The malaria disease has caused the mutation in the genes in the red blood cells which carries the oxygen to different organs of the body. The mutation in the genes causes the circular shape of red blood cell to sickle-shaped cells which carry less oxygen to the organs.
The change in the shape of red blood cell provides resistance against malaria disease but it becomes a problem where malaria is not a problem.
Thus, red blood cells (RBC) is the correct answer.

The question is about a test cross. Definition of a test cross: Generally a cross involving a homozygous recessive individual. When a single trait is being studies, a test cross is a cross between an individual with the dominant phenotype but of unknown genotype (homozygous or heterozygous) with a homozygous recessive individual. If the unknown is heterozygous, then approximately 50% of the offspring should display the recessive phenotype. If the individual is homozygous all the progeny will have the dominant phenotype. James' suggestion to use show the result of the two possible crosses with a Punnet square is a great suggestion.
