Solution

The correct option is D Intermittent light.
There is a linear relationship between incident light and CO2 fixation rates at low light intensities. At higher light intensities, gradually the rate does not show further increase. Increase in the light amount beyond a certain point causes the breakdown of chlorophyll. Thus photosynthesis is best when plant exposed to an intermittent light which means the light is not continuous but have enough shiny phases.
So, the correct option is 'Intermittent light'
