I did this by process of elimination:

Acne is not itchy or painful from my experience (Choice A).

Never heard of cutaneous lupus eryhtematosus, but I'd asssume you'd have a malar rash (involving the nose/undereye area), not spread out over the cheeks, jaw, and neck (Choice B).

Keloids are just overgrown scars. Scars are not particularly itchy or painful (Choice C)

Rosacea is just redness/flushing in certain areas of the skin. Mainly an aesthetic issue. Not itchy or painful (Choice E).

tbh I was between B and D.
