Given the following Java code, what method m will be executed when b.m() is executed.. class A { void m() {..} } class B extends A {void m() {..} } class Client { public static void main (String args[]) { A a = new A(); B b = new B(); b.m(); }}

a. Method m belonging to class B will be executed.
b.		Since B is a sub-class A, method m belonging to class B will be executed after method m belong to class A is executed. Super class methods are always executed first.
c.		Since B is a sub-class A, method m belonging to class A will be executed after method m belong to class B is executed. Sub class methods are always executed first.
d.		All other answers are wrong
