Rusting of iron requires which two conditions?

  1. Acid and oxygen
  2. Heat and pressure
  3. Water and oxygen
  4. Sunlight and water
Show answer and solution

Correct answer: C. Water and oxygen

Iron rusts in the presence of both moisture (water) and oxygen (from air). Pure dry air or pure water alone does not cause significant rusting.
