The Stop-and-Wait technique is primarily associated with c. Flow Control.

Explanation:

1. Definition: Stop-and-Wait is a method used in data transmission where the sender transmits a single frame and waits for an acknowledgment from the receiver before sending the next frame. This helps in managing the flow of data between sender and receiver to prevent overwhelming the receiving side.

2. Flow Control Context: In networking, flow control refers to techniques used to control the rate of data transmission between two nodes. The Stop-and-Wait protocol is a classic example of a flow control mechanism because it ensures that the receiver is ready to accept more data before the sender sends additional frames.

In summary, Stop-and-Wait is a flow control mechanism that helps maintain a balance in data communication by coordinating the transmission process between sender and receiver effectively.
