Solution

The correct option is A Cytokinin
Apical dominance:

The phenomenon in which the growth of lateral buds gets inhibited due to the growth of apical bud is known as apical dominance.

This is attributed to the action of auxin present at the apical regions of the root and shoot.

Cytokinin is antagonistic to the auxins in this aspect and helps overcome apical dominance.

Final answer: d. Cytokinin.
