Paulinella chromatophora is one of the few cercozoans that is autotrophic, carrying out aerobic photosynthesis with its two elongated "cyanelles."

-If true, which of the following is the best evidence that the cyanelles are providing nutrition (in other words, calories) to the surrounding cercozoan?

• A) if the cyanelle performs aerobic photosynthesis
• B) if the vesicle membrane that surrounds each cyanelle possesses glucose-transport proteins
• C) if the cyanelle performs aerobic respiration
• D) if radiolabeled 14CO₂ enters the cyanelle and if, subsequently, radiolabeled glucose is present in cercozoan cytosol
