Newton's first law of motion, also known as the law of inertia, states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. In this context, "inertia" is the tendency of an object to resist changes in its motion, which is the central concept of the first law. Therefore, the best choice is C.
