D Correct answer
Explanation

Melanin is the pigment produced by melanocytes in the skin that determines skin colour. It protects the skin from UV radiation and gives colour to hair, eyes, and skin. Haemoglobin gives red colour to blood, insulin regulates blood sugar, and adrenalin is a hormone for stress response.
