Correct answer: B
Correct answer: Replay attack
In a replay attack, the attacker records or captures a valid transmission and sends the same message again later.
The key clues are retransmits after some time and without altering the information. These point to delayed reuse of a genuine message.
The attack is different from impersonation alone or denial of service because the captured valid message itself is reused.
