Solution

The correct option is C ${G A}_{3}$
Gibberellic acid (GA $_{3}$ ) is a plant hormone which helps in growth of stem. The rapid flowering with cell division and cell elongation is called as bolting. Bolting requires either long days or cold treatment. Flowering can be induced in short day plants by application of GA $_{3}$ under normal condition.
Thus, the correct answer is option C.
