B
Correct Answer
The receive window size advertised by the receiver limits how much unacknowledged data the sender can have in flight, preventing receiver buffer overflow
Explanation
The receiver advertises rwnd (receive window) in ACKs. The sender limits in-flight bytes to min(cwnd, rwnd). Flow control prevents overwhelming the receiver; congestion control prevents overwhelming the network.
