Explanation:

To determine the variables affecting blood pressure, we recall the principles of cardiovascular physiology. Blood pressure (BP) is related to the formula \( BP = Cardiac\ Output \times Peripheral\ Resistance \), and blood volume also influences cardiac output and overall vascular pressure. Oxygen saturation relates to oxygen - carrying capacity of blood, not directly to blood pressure regulation. So Cardiac output, Blood volume, and Resistance to flow are the variables that determine blood pressure.

Answer:

A. Cardiac output, B. Blood volume, C. Resistance to flow
