Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Apical dominance is a phenomenon in which growth of shoot apex is dominant and the growth of lateral buds is suppressed. This results in vertical growth of plant. When the shoot tip is removed, the auxin concentration decreases. This results in growth of lateral buds. This whole process makes the plants bushy.
Thus, the correct answer is 'Both Assertion and Reason are correct and Reason is the correct explanation for Assertion'.
