Error in the code!!!

Question

do is a language reserved word so, it can not be a class, method, object name. If you run this code it will not compile. The answer should be B only if instead of do you name the class, object etc with anything other name.

Answer 1

"do" may do something in other languages, but in Java it has no purpose.

Answer 2

Running that code in the Code Playground, it doesn't compile.
I think "do" is a reserved work. Ex:

do {} while ();
