Question

which tool should be used when a fastener, such as a lug nut, is extremely tight?
a) ratchet
b) breaker bar
c) combination wrench
d) torque wrench

Explanation:

A breaker bar is designed to provide maximum leverage to loosen extremely tight fasteners like lug nuts. A ratchet is more for repetitive motion in a limited space. A combination wrench is a basic wrench without the extra leverage for very tight nuts. A torque wrench is for tightening to a specific torque, not for loosening extremely tight ones.

Answer:

B. Breaker bar
