The best answer to describe the major group of macromolecules that is protecting Brett's car is:
C. Lipids are protecting his car because their nonpolar nature makes them insoluble in water.
Wax, which is a lipid, forms a protective layer on the surface of the car, repelling water and preventing it from adhering to the surface. This helps to keep the car's paint protected from the weather.
