Prevotella melaninogenica can produce which pigment?

Explanation:
Prevotella melaninogenica is known for producing a melanin-like pigment, which gives dark, black pigmented colonies when grown on anaerobic blood-containing media. This pigment production is a characteristic feature that helps identify it in the lab, making black pigment the correct description. The other color options don’t match its typical appearance, as this organism usually does not form white, red, or pigmentless colonies.
