Answer: a. Excesses are eliminated from the kidneys.

Explanation:

A fat-soluble vitamin can be dissolved in fats and oils. They are absorbed along with fats in the diet from the intestinal lumen using the same mechanisms used for absorption of lipids. Upon absorption, these vitamins enter the lymph vessels before making they go into the bloodstream. In most cases, fat-soluble vitamins must be coupled with a protein in order to be transported through the organism. This means they are solubilized and transported by carrier proteins to exert their actions.

By last, since fat-soluble vitamins can not be dissolved in water, they are not readily excreted. So they can accumulate in fatty tissues to toxic levels if taken in excess.

harkovskaia [24]

If given a chance to advice Mr. Smith, I would recommend him to minimize going out in the sun when it is at the peak of the morning but if not possible since he works under the sun, it would be good to put on sunblock with a highest SPF and use precautionary measures like using hats and wearing long sleeve to protect also the skin. More water to hydrate, and vitamins for skin protection.
