Find output for below code :

public class Demo

public static void main(String[] arr) {

Integer num1 100;

Integer num2 = 100;

Integer num3 = 500;

Integer num4 = 500;

if(num1--num2) {

System.out.println("num1 = num2");

}

else{

System.out.println("num1 = num2");

}

if(num3 num4){

System.out.println("num3 num4");

}

else{

System.out.println("num3 = num4");

Choices:

a) num1 == num2

num3== num4

• b) num1 == num2

num3!= num4

c) num1 != num2

num3= num4

d) num1 != num2

num3 !=num4
