Since B is not one of the answer then A isn't.
only if the class is public then the name must be declared
the same as the class.

Good question..
You can have multiple classes in a single source file
But if you have any one of the class to be public
that class name MUST be the file name
But in this case its just MyProgram compile and run so we dont need MyProgram.java.
However main() is not required to be defined in the MyProgram class
class A {
public static void main(String args[]) {
System.out.println("Good luck");
}
}
class MyProgram extends A{}
Save in MyProgram.java OR A.java /compile/run it
