Which of the following statements regarding humidity is/are correct? 1. It is a ratio between the actual amount of water vapour present in the atmosphere and the maximum amount it can hold at a given temperature. 2. When the relative humidity is high, more water evaporates from the skin. 3. Higher the air temperature lower the relative humidity of the air. Select the answer using the code given below :

Statements 1 and 3 are correct. Relative humidity is indeed the ratio of the actual water vapour content in the air to the maximum amount it can hold at that temperature. As air temperature rises, the air's capacity to hold water vapour increases, so for the same absolute water vapour content, relative humidity decreases. Statement 2 is incorrect — when relative humidity is high, less water evaporates from the skin (the air is already nearly saturated), which is why hot humid weather feels more uncomfortable than hot dry weather.
