Solution
The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Stratification of seeds may affect the disappearance of inhibitors and the buildup of germination promoters such as the gibberellins and cytokinins. Natural stratification occurs when seeds shed in the fall are covered with cold soil, debris and snow. In artificial stratification, layers of seeds are alternated with layers of moistened Sphagnum sand or some other appropriated material are stored low temperatures.So, the correct answer is B 'Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion'
