Analyze the following code: public class test {public static void main(string[] args) {new b(); }}class a {int i = 7; public a() {seti(20); system. out. println("i from a is " + i); }public void seti(int i) {this. i = 2 * i; }}class b extends a {public b() {// system. out. println("i from b is " + i); }public void seti(int i) {this. i = 3 * i; }}a) the constructor of class a is not called. b) the constructor of class a is called and it displays "i from a is 60".c) the constructor of class a is called and it displays "i from a is 40".d) the constructor of class a is called and it displays "i from a is 7".
