The given scenario best illustrates Reinforcement theory.
Step-by-step explanation:
The theory that is used for changing the behavior through the process of controlling the behavior is called as a Reinforcement theory. This is also called a operant conditioning. Here there are two important things used to induce a behavior or eradicate a behavior. They are rewards and punishments.
In the given example, the furniture manufacturing company decides to give a reward as not to relocate to Ballowan only for those 10 employees who perform well in the next coming quarter. Thus this acts as a reward as well as punishments for those who do not perform well, as they should relocate to Ballowan. Thus, the theory of motivation used in this scenario is Reinforcement theory.
