T cells
The immune response to a transplanted organ consists of both cellular (lymphocyte mediated) and humoral (antibody mediated) mechanisms. Although other cell types are also involved, the T cells are central in the rejection of grafts. The rejection reaction consists of the sensitization stage and the effector stage.

C
Explanation:
Molecule C would be least soluble in water because it is not a polar compound/molecule. It also lacks any unit that can combine with water to form a good hydrogen bond. 
- The general rule of solubility is that like dissolves likes. 
- Polar molecules will only dissolve in polar solvent. 
- Water is a polar solvent with hydrogen bonds in them. 
- Hydrocarbons typically have weak london dispersion forces between them and they are not polar. 
- Other compounds have functional groups that can form hydrogen bond with water.

When a single copy of a disease allele doesn't result in a disease but instead is good for the person or organism that carries it, we say that allele has a heterozygote advantage. In other words this occurs when heterozyhotes have increased fitness over both homozygotes.  A good example is sickcle cell trait, which protects against malaria in heterozygotes, but causes a deadly disease in homozygotes.
