Which of the following is a common skin condition that may arise from stress?

The correct choice highlights a common skin condition that can be exacerbated or triggered by stress—psoriasis. Psoriasis is an autoimmune disorder characterized by the rapid buildup of skin cells, leading to scaling on the skin's surface. Stress is known to be one of the factors that can worsen the symptoms of psoriasis or even trigger its onset in individuals predisposed to the condition. Stress can lead to inflammation and can disrupt the body's immune response, influencing the development and exacerbation of psoriasis.

Other conditions like athlete's foot, sunburn, and cold sores may be associated with different factors. Athlete's foot is a fungal infection typically related to moisture and damp environments rather than stress. Sunburn is caused by overexposure to sunlight and UV radiation, which is unrelated to stress levels. Cold sores, while often triggered by factors such as illness, fatigue, or environmental stressors, are directly related to the herpes simplex virus. However, they are not classified in the same category of chronic skin conditions like psoriasis, which has a strong association with immune system responses linked to stress.
