Answer:
A
Explanation:
The stratum lucidum is the thin, clear layer of skin that lies between the stratum corneum and the stratum granulosum in the epidermis. It is only present in thick skin, such as the soles of the feet and palms of the hands, and is composed of flattened, dead keratinocytes that contain a protein called eleidin. The stratum lucidum helps to protect the skin from friction and abrasion.
