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.
