Answer:
The correct answer is: Perceptual Defense.
Step-by-step explanation:
The concept of perceptual defense can be understood as the tendency that individuals have to distort or "not perceive" certain elements or stimuli that may be unpleasant for the individual to acknowledge.
For instance, recognizing that a loved-one is committing infidelity or acknowledging that loyal employee is stealing from the company.
In this particular case, Kevin is experiencing perceptual defense because he is not acknowledging that one of his employees has been revealing confidential information to its competitors.
