Hint: To solve this problem you need to recall the concept of static friction. You can get this question right by applying the concept of static friction.

Complete step-by-step answer:

The maximum friction force that comes into play when the body is just starting moving is the limiting condition of static friction.

It is also called limiting friction.

As we know that static friction = ${f_s} = {\mu _s}N$, where ${\mu _s}$ is the coefficient of static friction and $N$is the normal force.

Static friction is the frictional force applied when the body is just about to move. It is also called limiting friction.

Hence, the correct option is C.

Note: To solve such problems we just need to know that static friction and limiting friction are the same. Therefore, the definition is also the same for both. This will help you to get the correct answer to this question.
