Model Answer

(C) Electroplating industry — heavy metals like lead and mercury

Explanation

The textbook explicitly states that electroplating industries release heavy metals like lead and mercury into water bodies. Fly ash is a solid waste (not linked to automobiles); petroleum refineries release acids/salts, not dyes/detergents; brick kilns cause air pollution via smoke, not water pollution with acids/salts.
