the answer is C

Explanation:

even small amounts of sun exposure are not healthy for our skin. sun exposure causes darkening, wrinkling, sun spots, in some cases acne, and freckle like damage. we dont have to completly avoid the sun, however an uncommon opinion or factor is that not being exposed to the sun is healthier than constantly being exposed to it. just because it gives vitamin d, does not mean not also unhealthy. i find that the less sun, the better. :)
