Answer 2

Answer:

The correct answer is option (b)

(b) Coolant level is low

Explanation:

• A vehicle will not start if the ignition switch is broken because ignition switch is the part which ignites fire in the engine cylinder.
• If the battery is faulty, the starting motor cannot be energized and hence it will lead to failure in starting of the automobile engine.
• The engine will also not start if the fuel injectors are blocked since sufficient fuel supply will not be available in the engine cylinder after the ignition.  
• The engine will start even if the coolant level is low. However, the engine temperature will rise and over heating warning symbol will be displayed on the dashboard of the automobile.
• The engine will starts again once the engine gets cool down.
• From the above it is clear that when the coolant level is low it will not lead to failure in starting of the automobile engine.

Answer: Option (b)
