Solution

The correct option is C Gibberellin
When gibberellins were applied to certain cold-requiring plants, they flowered without low-temperature treatment. Thus it is conceivable that gibberellins could induce certain changes within the plant which in turn lead to flowering. Thus option B is the correct answer.
