Which of the following statement is incorrect regarding bryophytes?

Which statement is correct for photosynthesis regarding light ?
(i) There is a linear relationship between incident light and CO₂ fixation rates at low light intensities
(ii) At higher light intensities, gradually the rate does not show further increase as other factors become limiting
(iii) Light saturation occurs at 10 per cent of the full sunlight. Hence, except for plants in shade or in dense forests, light is rarely a limiting factor in nature
(iv) Increase in incident light beyond a point causes the breakdown of chlorophyll and a decrease in photosynthesis
(v) When light intensity increase than first rate of photosynthesis increase then becomes constant due to CO2 becomes limiting factor
