Selection: The correct description of a catalyst is ( ). (A) Catalysts can speed up reaction rates, but their quantity keeps decreasing. (B) Catalysts are continuously involved in the reactions during use and eventually turn into other compounds. (C) Catalysts not only speed up reaction rates but also remain unchanged in terms of their properties and quantity before and after the reaction. (D) Catalysts can only speed up reaction rates
