Physical exam is notable for red papules and pustules scattered across the trunk, abdomen, back, and buttocks, while sparing the limbs. Closer examination indicates inflammation of the hair follicles. Culture yields motile, gram-negative rods that are non-lactose fermenting and oxidase positive. What other finding is commonly observed in the culture of the most likely organism?   (A) Pink colonies   (B) Blue-green pigment   (C) Yellow sulfur granules   (D) Red pigment
