Solution

The correct option is B Gibberellic acid
Gibberellic acid is a plant hormone which helps in growth of stem. It also brings about the rapid flowering in plants. It replaces the long day required for bolting in plants. It also helps in elongation of the internodes in such a way that dwarf plants overcome the genetic dwarfism. Hence, to overcome the genetic dwarfness, the plant is treated with gibberellic acid.
Thus, the correct answer is option B.
