You are presented with the question "What is likely to exert mutually on an object, making the object remain stationary?" and the following answer choices: 
- balanced forces
 - kinetic energy
 - a single force
 - competition
 - unbalanced forces
 - heat energy
 - randomized forces
 - solid, liquid, gas

Now knowing that if two balanced forces act on an object in opposite directions then that object will remain stationary and opposites also hold each other in balance and exert mutual control, choose the best answer.
