Correct answer
B. Flowering is either quantitatively or qualitative dependent on exposure to low temperature.
Step-by-step solution
Vernalization is the induction of a plant's flowering process by exposure to the prolonged cold of winter, or by an artificial equivalent. After vernalization, plants have acquired the ability to flower, but they may require additional seasonal cues or weeks of growth before they will actually flower.
