Show answerHide answer

Correct answer: (D) It ensures both the sender and receiver agree to close the connection.

Explanation

TCP connection termination is graceful: each side sends a FIN and the other acknowledges it (a four-way exchange), so both ends agree to close. It is not immediate and does use the FIN flag.
