D.

Psoriasis is a type of skin cancer that arises from melanocytes.

Answer and Explanation

The Correct Answer is C

Explanation: Psoriasis is a chronic skin disorder that results from an overactive immune response, leading to the rapid growth of skin cells. This causes red, raised, and scaly patches to form on the skin, which can be itchy and painful.

Incorrect choices: a. Psoriasis is not primarily an autoimmune disease affecting the respiratory system. It is primarily a skin condition, although it may be associated with certain autoimmune factors.

b. Psoriasis is not caused by a bacterial infection. It is a non-infectious skin disorder with an underlying immune-mediated mechanism.

d. Psoriasis is not a type of skin cancer. It is a benign skin condition that does not involve the malignant transformation of melanocytes.
