B

If both the assertion and reason are true but the reason is not a correct explanation of the assertion

C

Text Solution

Verified by Experts

The correct Answer is:
D
Auxin occurs in the growing apices of stem and roots from where they migrate to the site of action. Apical dominance is the phenomenon by which the presence of apical bud does not allow the nearby lateral or axillary buds to grow. Apical bud secretes auxin which inhibits the growth of lateral buds.
