Answer:
Defensive response.
Explanation:
Defensive response is the communication behavior in which the person gets defensive when he/she feels a certain kind of threat.
Such behaviors are caused when a person perceives that his/her voice is being suppressed. Defensive behavior can be communicated through change in tone, body language, etc.
In the given example, Ellen's behavior is a defensive response because her suggestion of a new proposal was ignored by her senior staff.
So, the correct answer is Defensive Response.
