The correct option is A Will not flower at all
Short day plants are those plants that require long period of darkness and short period of light to flower. Long day plants are those plants that will flower when they are exposed to short period of darkness and long period of light. Long day plants flower in summer and short day plants flower in spring. When the dark period of short day plants is interrupted by a brief exposure of light, the plant will not flower at all.
Thus, the correct answer is option A.
