Seborrheic Dermatitis involves oil production and yeast growth.

• A. It's caused by oil production and abundant Malassezia yeast
• B. It's caused by a bacterial infection
• C. It is not related to oil or yeast
• D. It is a form of skin cancer

Answer: (A)

Seborrheic dermatitis comes from the skin’s oil-producing glands working together with a yeast called Malassezia that thrives on that oil. In areas rich in sebum, Malassezia grows more than usual, and its lipid metabolism can irritate the skin, triggering inflammation, flaking, and redness. That’s why describing it as involving oil production and abundant Malassezia yeast captures the mechanism most accurately. The other options miss the biology: it isn’t driven by bacteria, it isn’t unrelated to oil or yeast, and it isn’t a form of skin cancer.
