D Correct answer
Explanation

6 mins is correct. The brain can typically survive without oxygen for about 4-6 minutes before irreversible cellular damage begins to occur. After approximately 6 minutes of oxygen deprivation, brain cells start to die due to lack of ATP production, leading to permanent brain damage. This is why immediate CPR and restoration of oxygen supply are critical in cardiac arrest cases.
