Refer the given figures on photoperiodism and select the correct option. A - Long light-exposure period, B - No correlation between light period and flowering, C - Short light exposure period.

A is a short day plant which requires longer duration of darkness and has less critical photoperiod. They flower when the night lengths exceed their critical photoperiod. For example, cotton. B is a long day plant which requires shorter duration of darkness and has longer critical photoperiod. They flower when the night length falls below their critical photoperiod. For example, pea. C is known as day neutral plant which do not depend on the length of the photoperiod. They flower regardless of photoperiod. For example rice.
