Solution
The correct option is C Intensity and quality Characteristics like intensity and quality of light affect the photosynthesis in plant. This in turn affects the growth and morphology of the plant. Monochromatic light reduces the growth in plants. Also, red and blue wavelengths of light have positive effect on photosynthesis. At high light intensity, the rate of photosynthesis decreases as it may damage the chlorophyll.
Thus, the correct answer is 'Intensity and quality.'
