Explanation:

To solve this, we analyze each option:

• Euthanasia: Refers to painless killing for mercy, not a gas from a truck tailpipe.
• Einsatzgruppen: Were mobile killing squads, not a substance.
• Untermensch: A derogatory term for "sub - human", not a killing agent.
• Carbon Monoxide: It is a gas that can be produced from a truck's exhaust (tailpipe) and was used by the Nazis in gas vans to kill victims.
