C.

D.

Answer 1

I don’t have the picture/context of which body system you mean. Here’s how the choices map to systems so you can pick:

- A (transports substances) — circulatory/cardiovascular system
- B (eliminates CO2) — respiratory system
- C (obtains nutrients) — digestive system
- D (protects from disease) — immune/lymphatic system

If the question referred to the circulatory system, the correct answer is A.
