The answer is the first one: At least 2 inches.

Explanation for each option:

  • At least 2 inches: This is the correct answer. According to the American Heart Association (AHA) guidelines, the recommended depth for chest compressions in adults is at least 2 inches (5 cm) to ensure effective circulation during CPR.

  • About 1½ inches: This is incorrect. Compressing only 1½ inches would not be sufficient to effectively circulate blood in an adult's body during CPR.

  • At least 3 inches: This is incorrect. Compressing more than 2.4 inches (6 cm) can cause injury to the ribs or internal organs, so 3 inches is too deep.

  • About 2 inches: This is incorrect. While "about 2 inches" might seem close, the guideline specifies "at least 2 inches" to ensure adequate compression depth.

In summary, the correct compression depth for adult chest compressions is at least 2 inches.
