Answer 1

Correct option is (b) Handshake connection The explanation: The WebSocket object provides the API for creating and managing a WebSocket connection to a server, as well as for sending and receiving data on the connection. The readonly attribute readyState represents the state of the connection. It can have the following values: A value of 0 indicates that the connection has not yet been established. A value of 1 indicates that the connection is established and communication is possible. A value of 2 indicates that the connection is going through the closing handshake. A value of 3 indicates that the connection has been closed or could not be opened.
