Explanation

For answer A

The lack of antifreeze in the coolant does not cause an increase in fuel consumption, it is added to prevent the coolant from freezing during winter.

For answer B

If the steering system is manual, it means that it does not include other electrical or hydraulic mechanisms, it has no impact on fuel consumption.

For answer C

Electrical devices powered by the motor vehicle’s generator (by the alternator) increase fuel consumption. The alternator is the main component of the car’s electric current generating system.

The correct answer is: C
