Solution

The correct option is D Gibberellins
Gibberellin is a plant hormone which helps in growth of stem. The rapid growth and flowering is called as bolting. Bolting requires either long days or cold treatment. However, it can be induced artificially by the application of gibberellin under normal conditions. Hence, it replaces the long day conditions required for flowering. It also controls sex expression in many plant species. It promotes maleness in flower.
Thus, the correct answer is option C.
