B Correct answer
Explanation

Melanin is the pigment primarily responsible for skin color in humans. It is produced by melanocytes in the basal layer of the epidermis and transferred to keratinocytes. Melanin absorbs UV radiation, protecting deeper skin layers from damage. Option A (anthocyanin) is a plant pigment, Option C (haemoglobin) gives red blood cells their color, and Option D (carotenoid) is an orange/yellow plant pigment that can affect skin tone slightly but is not the primary determinant of skin color.
