A developer is setting up a new Node.js server with a client library that is built using events and callbacks.
The library:
* Will establish a web socket connection and handle receipt of messages to the server
* Will be imported with require, and made available with a variable called we.
The developer also wants to add error logging if a connection fails.
Given this info, which code segment shows the correct way to set up a client with two events that listen at execution time?

• A.ws.on ('connect', ( ) => {
  console.log('connected to client'); ws.on('error', (error) => { console.log('ERROR' , error); });
  });
• B.ws.on ('connect', ( ) => { console.log('connected to client'); }}; ws.on('error', (error) => { console.log('ERROR' , error); }};
• C.try{
  ws.connect (( ) => {
  console.log('connected to client'); });
  } catch(error) { console.log('ERROR' , error); };
  }
• D.ws.connect (( ) => {
  console.log('connected to client'); }).catch((error) => { console.log('ERROR' , error); }};
