Which of the following conditions is an autoimmune disease that is typically hereditary and not contagious?

Explanation: Psoriasis is a non-contagious autoimmune disease where the body mistakes the skin as a pathogen and sends faulty messages to speed up the growth of skin cells. There are five types but the most common is plaque psoriasis which exhibits scaly, red and white patches of skin. Massage is contraindicated directly over the affected area but indicated over unaffected skin.
