Question

to tighten the wheel lug nuts to the proper torque a torque wrench should be used, however, you could also use: a) an air driven impact b) a breaker bar with the correct socket c) an impact with the correct torque stick d) an adjustable wrench with a torque meter

Explanation:

An air - driven impact alone doesn't ensure proper torque. A breaker bar is mainly for loosening tight nuts. An adjustable wrench with a torque meter is not a common or reliable way. An impact with the correct torque stick can be used to tighten wheel lug nuts to the proper torque as the torque stick limits the amount of torque applied.

Answer:

C) an impact with the correct torque stick
