The correct option is C Light is required in long day plant only for flowering
The response of flowering plant due to the effect of relative length of the day and night is called photoperiodism. Photoperiodic stimulus is perceived by mature leaf and mediated by florigen hormone for flowering. Due to this, shoot apices modify themselves into flowering apices prior to flowering.
Light is required in long day plant as well as short day plant for flowering.
