Step 1: Identify the definition of each term provided.
A. A mole is a type of skin growth that can appear anywhere on the body. It is usually brown or black and can vary in size. B. A callus is a toughened area of skin which has become thick and hard in response to repeated friction, pressure, or other irritants. C. A bunion is a bony bump that forms on the joint at the base of your big toe. It forms when your big toe pushes against your next toe, forcing the joint of your big toe to get bigger and stick out.
Step 2: Based on the definitions, identify the correct answer.
The question asks for thick accumulations of dead keratinocytes, which are cells found in the outermost layer of the skin. From the definitions, a callus is the best match as it is a toughened area of skin which has become thick and hard in response to repeated friction, pressure, or other irritants.
Final Answer
Calluses.
