Overview
Explanation
The correct answer is C. The stratum basale is the single layer of the epidermis. All of the keratinocytes are produced from this single layer of cells, which are constantly going through mitosis to produce new cells. Cell division does not occur in the stratum lucidum, stratum granulosum, or the stratum reticularis.
