The correct answer is **d) All of the above**.
Newton's Third Law states that for every action, there is an equal and opposite reaction. Each of the options provided illustrates this principle:
- **A horse pulling a horse cart:** The horse applies a force on the cart, and the cart applies an equal and opposite force back on the horse.
- **A hammer striking a nail:** The hammer exerts a force on the nail, and the nail exerts an equal and opposite force on the hammer.
- **A soccer ball bouncing off a wall:** The ball applies a force against the wall, and the wall applies an equal and opposite force back on the ball, causing it to bounce away.
Thus, all of these examples demonstrate Newton's Third Law of motion.
