Final answer:
The correct answer is option B: Chloe pulls the corner of her dresser, and the dresser stays still. The example of balanced forces is when Chloe pulls on her dresser but it doesn't move, indicating that the opposing forces are equal and cancel each other out.
Step-by-step explanation:
The sentence that describes an example of balanced forces is: Chloe pulls the corner of her dresser, and the dresser stays still. In this situation, the forces exerted by Chloe and the frictional force or any other opposing resistance are equal in magnitude but opposite in direction, resulting in no movement of the dresser, indicating that the forces are balanced.
