A Correct answer
Explanation

Newton's first law states that an object remains at rest or in uniform motion unless acted upon by an external force. The question incorrectly phrases it as 'force, inertia must act' - inertia is the property that resists change in motion, not something that acts. The correct concept is that force causes change in motion.
