Question

how could carbon monoxide gas enter your vehicle compartment?
○ through leaks in the exhaust system
○ from windy conditions
○ by running the vehicle in an enclosed environment, such as a garage
○ both a and c

Explanation:

Carbon monoxide (CO) is a by - product of incomplete combustion. The exhaust system is designed to channel CO away from the vehicle compartment. If there are leaks in the exhaust system (Option A), CO can seep into the compartment. When a vehicle is run in an enclosed environment like a garage (Option C), the concentration of CO can build up outside the vehicle, and if there are any openings (even small ones) in the vehicle's structure (or if the ventilation system is not functioning properly), CO can enter the compartment. Windy conditions (Option B) do not directly cause CO to enter the vehicle compartment as CO is not generated or forced in by wind in a normal vehicle operation scenario.

Answer:

D. both A and C
