You have to remember that everything you put in a scriptlet will go into a method. So you cannot define a new function in scriptlets, you have to use declarations instead. Therefore, both 1 and 5 can be discarded.

Strange, I thought option 4 was incorrect, because of the final semicolon, but it compiles alright. How does this fit into Java syntax? Is it something like an "empty field definition"?
