c. CAM plants are more efficient at producing sugar than C4 plants regardless of environmental conditions.
d. CAM plants produce a 4-carbon molecule in the first step of carbon fixation, but C4 plants do not.
e. CAM plants are limited to producing CO2 for the Calvin cycle during the day, while C4 plants produce CO2 for the Calvin cycle both during the day and at night.

I think the correct answer is E.
