Solution
The correct option is C Short day
When the dark period is interrupted by the flash of light, the plant could not produce flowers because the dark period could not reach the critical requirement. It shows that the plant needs a long dark period than the light period. So, it is a short day plant.Hence, the correct answer is 'Short day'
