C Correct answer
Explanation

Hydrothermal vents on the ocean floor emit superheated mineral-rich water. Black smokers are the hottest, with temperatures reaching over 750°F (400°C), and appear dark because the dissolved minerals precipitate into black particles when the hot water meets cold ocean water, giving them their characteristic appearance.
