Solution
The correct option is B Gibberellin
Bolting is a survival mechanism in a plant. It is the elongation of flowering stem before the crop is harvested to produce seeds. This helps in increased reproduction. Crops like lettuce, basil, onion, etc are usually bolted. It is induced by artificial treatment with plant hormone gibberellin. It causes stem elongation in plants under normal condition. Prior to flowering, internodes elongate enormously resulting in bolting. Thus, the correct answer is option D.
