The correct answer is B. Glycolysis.
Glycolysis is the first step of cellular respiration that occurs in the cytoplasm of the cell. During glycolysis, one molecule of glucose is broken down into two molecules of pyruvate, producing a small amount of ATP (energy) and NADH in the process. This step does not require oxygen and sets the stage for the subsequent stages of cellular respiration.
