CO2 production first occurs during the Pyruvate oxidation stage of cellular respiration.

Here's a step-by-step breakdown of the process:

1. Glycolysis: This is the first stage of cellular respiration and occurs in the cytoplasm of the cell. One glucose molecule is broken down into two molecules of pyruvate. However, no CO2 is produced in this stage.

2. Pyruvate Oxidation: This is the stage where CO2 production first occurs. Each pyruvate molecule is oxidized to form a molecule called Acetyl CoA. During this process, one molecule of CO2 is released for each pyruvate.

3. Citric Acid Cycle (also known as Krebs cycle or TCA cycle): This occurs in the mitochondria. Here, each Acetyl CoA is further broken down and more CO2 is produced.

4. Oxidative Phosphorylation: This is the final stage of cellular respiration where the majority of ATP is produced. However, no CO2 is produced in this stage.

5. Anaerobic Respiration: This is a type of respiration that occurs when there is no oxygen present. It does not produce CO2.

So, the answer to your question is b. Pyruvate oxidation.
