Solution

The correct option is B
Gibberellins

Gibberellins induce internodal elongation. For example, corn is short in stature because of a defect in Gibberellic acid biosynthesis and its short stature can be overcome by gibberellic acid.

Cytokinins promote cell division.

Ethylene helps in fruit ripening.

Indole acetic acid plays a key role in both root and shoot development.
