Which danger exists to people when CO2 is discharged into a small enclosed space?

A Respiratory arrest
B Damaged eardrums
C Frostbite
D Electric shock
AI Explanation

The correct answer is A) Respiratory arrest. When CO2 is discharged into a small enclosed space, it can displace the oxygen in the air, leading to a dangerous lack of oxygen. This oxygen deficiency can cause respiratory arrest, where the person's breathing stops. The other answer choices are incorrect because they do not accurately describe the primary danger of CO2 discharge in an enclosed space. Damaged eardrums, frostbite, and electric shock are not the direct risks associated with CO2 exposure in this scenario.
