Answer Key / Explanation : (b) -

(b)

When long day plants are grown under short day conditions, the gibberellins are produced in insufficient quantities and flowering does not occur. However, if the plant is transferred to long day conditions, or gibberellin solution is applied to leaves, flowering occurs.
