Newtons 1st law of motion states:

An object in motion will stay in motion and an object in rest will stay in rest unless acted upon by and unbalance force.

For every action there is an equal and opposite reaction.

Acceleration is produced when a force. acts on a mass.

The greater the mass the greater the amount of force needed to change its motion.

Which example below demonstrates Newton's third law of motion the best?

When a boxer lands a powerful hit on his or her opponent the opponent loses composure or can even get knocked down.

It takes more force for a boxer to knock out a larger opponent vs a smaller opponent.

Sometimes when a boxer is warming up by running but they can be slowed down if there is traffic in the road.

There are only two laws of motion.
