Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
In arid and unirrigated areas crop plants cannot be grown because of excessive transpiration and reduced water availability. Substances that reduce the rate of transpiration are called antitranspirants. e.g. ABA. Antitranspirants like ABA will prevent excessive loss of water due to transpiration through stomata, as ABA mediates in closure of stomata.
So, the correct solution is B 'Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion'
