Show answer & explanation
Correct answer: C
In Stop-and-Wait ARQ, the sender sends one frame and waits for its acknowledgment before sending the next.
For every data packet sent, one ACK (acknowledgement) is received
There is no extra or missing ACK per packet
So:
10 data packets → 10 acknowledgements
