Answer:

d. Neither A nor B

Explanation:

Mostly for exhaust bolts we use impact wrenches. Impact wrenches are very useful on flywheels because the crank shaft needs to be fixed from rotating. Also impact wrenches are useful on cars for loosening wheel nuts.  The wheels need not to be restrained or the brakes need not to be applied to fiz wheels in position.
