b. 50 compressions should be followed by 2 rescue breaths.

d. elbows should be relaxed.
please select the best answer from the choices provided.

Explanation:

• Option A: Current CPR guidelines recommend chest compressions to be at least 2 inches (5 cm) but not more than 2.4 inches (6 cm) for adults, so 2.5 - 3 inches is incorrect.
• Option B: The standard ratio for CPR is 30 compressions followed by 2 rescue breaths, not 50.
• Option C: The rate of chest compressions should be 100 - 120 compressions per minute, so 100 compressions every minute is within the correct range.
• Option D: Elbows should be locked during chest compressions to ensure proper force is applied, not relaxed.

Answer:

C. 100 compressions should be performed every minute.
