Final answer:
A defensive person is usually described as cautious.
Step-by-step explanation:
In the context of personal or professional communication (PC), describing someone as "defensive" typically means that the person tends to react to criticism, feedback, or challenging situations with a protective or guarded stance. They may feel the need to justify themselves, deflect blame, or resist accepting responsibility. This defensive behavior can be a response to perceived threats, criticism, or challenges to their beliefs or actions.
