What is the purpose of 'cracking' a cylinder before use?

A) This primes the system with oxygen so there is no air mixed in with the oxygen with the first part of the gas delivered to the patient.
B) This removes any dust,or particulate matter,from the outlet of the cylinder valve.
C) It causes the regulator to become pressurized precisely to 50 psi before gas is delivered to the patient.
D) It pressurizes the cylinder to make sure it will not leak and compensate for the cylinder until the cylinder is hydrostatically tested.
