Show answer & explanation
Correct answer: B
Normal water is neutral with a pH of 7. Rainwater is slightly acidic due to dissolved CO2, typically around pH 5-6. Acid rain has a lower pH, usually below 5. Ocean water is alkaline with a pH greater than 7. Therefore, the correct matching is A-IV, B-III, C-I, D-II.
