An inertial frame is a frame of reference in which there are no accelerations without applied forces. This concept is a fundamental aspect of Newton's laws of motion, which state that an object will remain at rest or continue in a straight line at a constant velocity unless acted upon by a net external force. In an inertial frame, this principle holds true without any additional factors, such as the effects of relativity or the violation of any of Newton's laws. Therefore, option C is the best definition of an inertial frame.
