Solution
The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Vernalization is a process of induction of dormancy in plants in cold temperatures by artificial methods. It helps certain plants prepare for the following year. Plants under such conditions must be exposed to a certain number of days of cold temperatures below a certain threshold. After vernalization, the plants are capable of flowering. In years, regions or techniques which does not provide enough chilling time, these plants will produce a poor crop or, in some cases, they will not flower or produce fruit at all. So, flowering is affected by vernalization.
So, the correct option is 'Both Assertion and Reason are correct and Reason is the correct explanation for Assertion'.
