Solution

The correct option is A Long day plants under short day conditions
Gibberellic acid 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 by application of gibberellic acid under normal conditions. It induces flowering in long day plants under short day conditions.
Thus, the correct answer is option C.
