The condition shows that the plant requires a photo-period shorter than the critical day length.

This plant needs an uninterrupted dark period for hovering. Therefore, it is a short-day plant and these do not flower if the dark period is interrupted with flashes of light.

Hence, the correct answer is option 4.
