The correct answer is B: carbon dioxide and water.
During cellular respiration, glucose (a carbohydrate) and oxygen are converted into carbon dioxide, water, and energy (in the form of ATP). The overall equation for cellular respiration can be summarized as follows:
\[ \text{C}6\text{H}{12}\text{O}_6 , (+ , 6 , \text{O}_2) \rightarrow , 6 , \text{CO}_2 , + , 6 , \text{H}_2\text{O} , + , \text{Energy (ATP)} \]
So the primary products of cellular respiration are carbon dioxide (CO₂) and water (H₂O).
