Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Apical dominance is the term used to describe the control of the shoot tip over axillary bud outgrowth. It is best demonstrated via shoot tip removal (decapitation), which leads to apical dominance. Pruning is a horticultural practice involving the selective removal of parts of a plant, such as branches, buds, or roots. The cultivation of mulberry plants for harvesting the leaves to be used for the sikworms is called moriculture. The mulberry tree has a spreading habit and so it is pruned to promote development of apical bud and not lateral buds.
So, the correct answer is option B.
