Solution
The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
70% of the Earth's surface is covered with water but this water is not usable because of its saline nature. Only 1% of the available water is useful for drinking and other uses. So, inspite of having such a large quantity of water on the Earth, we face severe water scarcity. Water gets evaporated from water bodies in the form of water vapour. Water vapour is the gaseous form of water.
So, both assertion and reason are correct but the reason is not the correct explanation for assertion.
