A Correct answer
Explanation

Melanin is the pigment responsible for giving color to skin, hair, and eyes. It's produced by specialized cells called melanocytes and provides protection against harmful UV radiation from the sun. The other options are incorrect: Nicotine is a stimulant found in tobacco, bilirubin is a waste product from red blood cell breakdown that causes jaundice, and hemoglobin is the red pigment in blood that carries oxygen (not responsible for baseline skin color).
