Law of Inertia:

The Law of Inertia, also known as Newton's First Law of Motion, states that an object at rest tends to stay at rest, and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an external force. This law describes the tendency of objects to resist changes in their state of motion.

Explanation:

The correct answer is option 'D' - All of these.

- Soccer: In soccer, the Law of Inertia is evident when the ball is stationary on the field. The ball will remain at rest until a player applies a force to kick or move it. Similarly, once the ball is in motion, it will continue to move in a straight line at a constant speed unless acted upon by external forces such as friction or a player intercepting it.

- Softball: In softball, the Law of Inertia is observed when a pitcher throws the ball. The ball will continue to move in the same direction and at the same speed unless acted upon by external forces like air resistance or the impact of a bat or glove.

- Basketball: In basketball, the Law of Inertia is demonstrated when a player dribbles the ball. The ball will continue to bounce up and down in a regular pattern unless an external force, such as the player's hand or the floor, acts upon it.

Conclusion:

All of the given options - Soccer, Softball, and Basketball - provide examples of the Law of Inertia. In each case, the objects (ball) involved will either remain at rest or continue in motion until an external force is applied to change their state. This demonstrates the fundamental principle of inertia, as explained by Newton's First Law of Motion.
