Short day (SD) plants flower when night lengths are longer than a critical dark period. Interruption of the dark period by a brief light treatment prevents flowering in SD plants. Long day (LD) plants flower when night length is shorter than a critical period. Shortening of the night with a brief light treatment induces flowering in LD plants. Therefore option a is correct. Hence, the correct answer is option 1.
