The task presents two prompts that map to the same set of possible answers. I will evaluate each prompt separately, explaining why each option fits or does not fit.

Prompt 1: Pulmonary, tricuspid, aortic, and mitral valves
- Option: act as gates that open and close once with each heartbeat to prevent backflow of blood
  This description correctly characterizes heart valves in general. Valves function as one-way gates that open and close in coordination with the cardiac cycle to prevent backflow, ensuring unidirectional blood flow through the heart and great vessels.
- Option: prevent mixing of oxygen-rich with oxygen-poor blood
  This statement is true of the overall circulatory system as a principle, but it is not the primary or specific role of valves such as the pulmonary, tricuspid, aortic, and mitral valves. The mixing of oxygen-rich and oxygen-poor blood is more about the separation of systemic and pulmonary circuits rather than the core mechanical function of a single valve.

Prompt 2: Division of heart into right and left side
- Option: act as gates that open and close once with each heartbeat to prevent backflow of blood
  While valves perform this gate-like function, this option does not describe the structural division of the heart into right and left sides. The statement is more about valve function than about the anatomical separation of the heart chambers.
- Option: prevent mixing of oxygen-rich with oxygen-poor blood
  This option directly references the functional consequence of separating the heart into right and left sides. The right side handles deoxygenated blood, the left side handles oxygenated blood, and the separation by the septa and chambers minimizes mixing between the two streams.

Across both prompts, one option aligns with the explicit role or consequence described by the prompt. The gate-like mechanism aligns with the general valve function, while the separation of right and left sides aligns with preventing mixing of differently oxygenated blood. The explanations above connect each choice to the underlying physiology, clarifying why each statement is accurate or less appropriate depending on the prompt context.
