Final answer:
The phenomenon of a person sliding to the right when a car sharply turns to the left is an example of Newton's First Law of Motion, which is also known as the law of inertia. So the correct option is A.
Step-by-step explanation:
When a car takes a sharp turn to the left and the person inside slides to the right, this is an example of Newton's First Law of Motion, which is often referred to as the law of inertia. This law states that an object will continue to be at rest or move at a constant speed in a straight line unless acted upon by an outside force. In the scenario described, the person in the car is initially moving forward with the car. When the car suddenly turns to the left, the person continues to move in their original direction (to the right, relative to the car) until a force (such as the door or seatbelt) acts upon them to change their motion, thus demonstrating inertia.
