The correct option is 3) wearing a seat belt in a car
Explanation:
- According to Newton's first law of motion, an object at rest or an object in uniform speed will continue to be so until an external force is applied on it.
- When brakes are applied, the external force does not remain constant. As a result the body of an individual tends to move forward when sudden brakes are applied, the seat belt tends to grasp the force and prevent the person from moving forward.
