B. flowering that is either quantitatively or qualitatively dependent on the exposure to low temperature.
Step-by-step solution
Vernalization is the induction of a plant's flowering process by exposure to the prolonged cold in winter or by an artificial equipment. After vernalization, plants acquire the ability to flower, but they may require additional seasonal cues or weeks of growth before they actually flower.
