Explanation:

Analyze the purpose of a carbon monoxide detector

Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that is highly toxic when inhaled. Because humans cannot detect it using their senses, a specialized electronic detector is required to sound an alarm and prevent carbon monoxide poisoning.

Evaluate the given options

• to prevent an allergic reaction: Incorrect. Carbon monoxide is a systemic toxin, not an allergen.
• to prevent poisoning from carbon monoxide: Correct. The detector alerts residents to dangerous levels of the gas, allowing them to evacuate and prevent poisoning.
• to warn members of the household of smoke from a fire: Incorrect. This is the function of a smoke detector, not a carbon monoxide detector.

Answer:

• to prevent an allergic reaction
• to prevent poisoning from carbon monoxide (Correct answer)
• to warn members of the household of smoke from a fire
