Box 3 is bullsh... Hub invokes on 'hello' function that passes 'message' variable: hub.on('hello', function(message){ $('#message').text(message); } );

I'm not sure. Your link show using method start without delegate. See: https://docs.microsoft.com/en-us/aspnet/signalr/overview/guide-to-the-api/hubs-api-guide-javascript-client#the-generated-proxy-and-what-it-does-for-you

The third code segment is nonsense as already said by Ekovalev. So FINAL ANSWER: FINAL ANSWER: $.hubConnection(); con.createHubProxy("MyHub") hub.start('hello', function(message) {

I can confirm they haven't changed the code segments in the exam. I chose hub.on('hello', function(message) because it is the only syntactically correct.
