Analogy — Supports vs suppresses combustion: Oxygen : Burn :: Carbon dioxide : ? Pick the effect that carbon dioxide has with respect to fire.

Introduction / Context:Oxygen supports burning; carbon dioxide suppresses it. Therefore, “Extinguishes” best mirrors the complementary combustion effect.

• Explode: Opposite implication.
• None of these: Invalid since “Extinguishes” is standard in fire safety.

Final Answer:Extinguishes
