Analyze the following code:
``` public class Test { public static void main(String[] args) { B b = new B(); b.m(5); System.out.println("i is " + b.i); } } class A { int i; public void m(int i) { this.i = i; } } class B extends A { public void m(String s) { } }``` a. The program has a compile error, because m is overridden with a different signature in B. b. The program has a compile error, because b.m(5) cannot be invoked since the method m(int) is hidden in B. c. The program has a runtime error on b.i, because i is not accessible from b. d. The method m is not overridden in B. B inherits the method m from A and defines an overloaded method m in B.
