multiple-choice question
melanin gives us ______________ skin
different colored
tougher

Explanation:

Melanin is a pigment produced by melanocytes, and its primary role related to skin is to determine skin color (different levels of melanin production lead to different skin colors). The "tougher" property of skin is more related to the keratinization process of keratinocytes, not melanin. So the correct option is the one related to skin color.

Answer:

A. different colored
