With reference to water vapour, which of the following statements is/are correct?

It is a gas, the amount of which decreases with altitude. Its percentage is maximum at the poles. Select the answer using the code given below : (a). 1 only (b). 2 only (c). Both 1 and 2 (d). Neither 1 nor 2 Explanation: Statement 1: Correct. Water vapor is indeed a gas, and its concentration generally decreases with altitude due to lower temperatures and pressure at higher altitudes Statement 2: Incorrect. Water vapor content is generally higher in warmer regions, near the equator, and decreases towards the poles due to lower temperatures. Therefore, the correct answer is (a): 1 only
