Answer 1

If the fuel tank vent on a diesel-powered vehicle is plugged, the engine would shut down due to fuel starvation.

Step-by-step explanation:

If the fuel tank vent on a diesel-powered vehicle is plugged, the likely outcome when running the engine would be c) the engine would shut down due to fuel starvation.

The fuel tank vent is responsible for allowing air to enter the tank as fuel is consumed, preventing a vacuum from forming. If the vent is plugged, no air can enter the tank, leading to fuel starvation as fuel is consumed and no air can replace it.
