a. Mine wastes and heavy metals become water pollution through storm water runoff.

Brief explanation: mining wastes and heavy metals are commonly transported into surface and groundwater by runoff and leaching (including acid mine drainage). The other statements are false: biodegradable organic matter can cause oxygen depletion, petroleum enters water from many sources besides big spills, and pesticides/herbicides frequently contaminate water via runoff and leaching.
