Answer 1

This dark mass on the skin, a form of skin cancer, is directly due to the uncontrolled mitosis and growth of abnormal cells. Option a is the correct answer. Skin cancer occurs when mutations in skin cells lead to uncontrollable cell division and the formation of tumors. These abnormal cells grow and divide rapidly, leading to the development of a dark mass on the skin. The other options mentioned in b, c, and d are not directly related to the development of skin cancer.
