There are two plants A and B with respective critical photoperiod of 13 hours and 11 hours. When they are exposed to light for a period of 12 hours, it initiated flowering in both. Which of the following conclusions is most appropriate for these plants?

Step-by-step solution

Plant A is a short-day plant (A plant that flowers only after being exposed to light periods shorter than a certain critical length.) and plant B is a long-day plant (A plant that flowers only after being exposed to light periods longer than a certain critical length).
