The correct choice is the fourth. Inertia is the tendency of an object to keep doing what it's doing: stay at rest unless a force moves it, or keep moving at the same speed and direction unless a net force (like friction, air resistance, or a push) changes that motion. Mass measures how much inertia an object has.
