That would be C. The control group is the group where no variable has been changed for it and it’s how something normally would be.
For example if we’re experimenting the effect of excess water on plant growth the plant getting normal amount of water is the control group and the plant getting excess water is the test group(or groups in most cases there is more than one).

The stretch of the integral protein within the hydrophobic interior of the bilayer is also hydrophobic, made up of non-polar amino acids. Like the lipid bilayer, the exposed ends of the integral protein are hydrophilic. When a protein crosses the lipid bilayer it adopts an alpha-helical configuration.
