A) Melanocytes

Ans: A
Feedback:
In addition to the keratinocytes, the epidermis has melanin pigment–producing melanocytes that protect against ultraviolet radiation and Langerhans cells that link the epidermis to the immune system. Subcutaneous tissue contains fat and binds the dermis to underlying body tissues. The third keratinocyte layer, the stratum granulosum, is composed of flat cells containing protein granules called keratohyalin granules.
