What statement about an object moving in a straight line through air is correct

• When it accelerates, the resultant force is 0N
• When it moves at a constant speed, the force of the air resistance is 0N
• When it moves, there is always a resultant force acting on it
• When it moves at a constant speed, the resultant force is 0N
