Solution
The correct option is B Gibberellins
Vernalization is acquisition of ability of plants to flower by chilling treatment. In absence of cold treatment, accumulation of ent-kaurenoic acid in shoot tip occurs. Cold treatment followed by exposure to high temperatures convert it into GA9, which stimulates flowering response in plants. Thus, gibberellins can substitute the vernalization. Thus, option B is correct.
