What is the main advantage for plants that use the C₄ pathway in addition to the Calvin cycle for the fixation of carbon dioxide?
A)Fewer ATP are consumed to produce carbohydrates using the C₄ pathway as opposed to the Calvin cycle.
B)The C₄ pathway allows for fixation of carbon dioxide at night.
C)The C₄ pathway aids in the avoidance of the oxygenation of ribulose 1,5-bisphosphate.
D)The C₄ cycle allows photosynthesis to occur at a wide range of wavelengths of light.

The C₄ pathway aids in the avoidance of the oxygenation of ribulose 1,5-bisphosphate, which can occur in the Calvin cycle in plants that do not have the C₄ pathway. This ensures that carbon dioxide is efficiently fixed and not wasted in the process.
