Final Answer :
B
Explanation :
The stratum spinosum, also known as the "spiny layer" due to the appearance of the cells caused by the desmosomes that hold them together, is composed of several layers of living keratinocytes. These cells are still alive and are characterized by their ability to provide strength and flexibility to the skin.
