Show answer & explanation
Correct answer: A
Pure rainwater is naturally acidic due to dissolved carbon dioxide forming carbonic acid, resulting in a pH of approximately 5.6 rather than 7 (neutral). Therefore, option A is correct and options B, C, and D are incorrect. Rainwater with a pH less than 5.6 is defined as acid rain, making option E correct.
