Detailed Solution

Statement (A): In plants of shade and dense forest light is a limiting factor for photosynthesis.
Statement (B): There is a linear relationship between the incident light and CO₂ fixation rates at lower light intensities.

The relationship between incident light and CO₂ fixation rates is not always linear, especially at higher light intensities.

The rate of photosynthesis may reach a point of saturation where further increases in light intensity do not result in proportional increases in CO₂ fixation. Instead, other factors such as the availability of enzymes or other resources may become limiting.
