Newton's First Law of Motion states that an object at rest will stay at rest, and an object in motion will continue in motion at a constant speed and in a straight line unless acted upon by an unbalanced force.
Among the examples you provided, the closest one that illustrates Newton's First Law is:
"A tennis player throws the tennis ball into the air for a serve and the ball falls to the ground."
This example demonstrates the idea of an object (the tennis ball) being in motion (upwards) and then being affected by gravity (an unbalanced force), causing it to change its state of motion (falling to the ground).
The other options, while they may involve motion, do not specifically highlight the concept of inertia or an object's resistance to changes in its state of motion as clearly as the ball example does.
