A. Presence of iron and its reaction with water and oxygen.

Explanation: The red color comes from iron-bearing minerals in the rock that oxidize (weather) to form iron oxides like hematite and limonite, which produce red/orange hues. Copper gives greens/blues, sulfur gives yellows, and nitrogen oxides do not produce the typical red rock coloration.
