Selected Answer: B
WebSockets are a communication technology that enables real-time data exchange between a client (such as a web browser) and a server. Unlike the traditional request-response model of HTTP, WebSockets establish a persistent connection, allowing the server to send data to the client at any time, without the client having to make a request.
