Answer»

The correct ANSWER is (a) O2 and N2O

Easiest explanation: In general ANESTHESIA, the gases are given through a face mask. Oxygen is given to allow normal breathing while nitrous oxide is given to anesthise the patient. However, in MAJOR OPERATIONS, nitrous oxide is USED more as a carrier gas as it alone is not powerful enough to anesthise the patient.
