Which of the following statements about psoriasis is true?

• A. It is contagious through touch
• B. It disappears without treatment
• C. It is usually found in patches on the scalp, elbows, knees, chest, and lower back
• D. It affects only adults

Answer: (C)

Psoriasis is a chronic inflammatory skin condition that causes red, scaly plaques. A common pattern for plaque psoriasis is patches on the scalp, elbows, knees, chest, and lower back, which is why this statement is true. It is not contagious—you can’t spread it by touch. It does not disappear on its own and tends to be persistent, though it can be managed with treatments such as topical therapies, phototherapy, or systemic medications. It can affect people of any age, not just adults.
