Not sure what is wrong with this question and answers, I could not see a difference between B and C.

Am I missing something or is there a typo in the question and answers? http://imgur.com/a/2NTcA Screenshot of Questions

The difference is that answer B encloses the function in parenthesis ( and ) instead of braces { and }:

function sayHello() ( // ( should be {
  alert('Hello')
) // ) should be }

It's not a very visible difference depending on the font used, but it's a big difference as far as JavaScript is concerned.
