Answer C:
This is because obj2 is referring to obj1. Therefore, the assignment obj2.var = ‘o’ is reflected in obj1.

public static void main(String[] args) {
char var1 = ‘a’;
char var2 = var1;
var2 = ‘e’;
Vowel obj1 = new Vowel();
Vowel obj2 = obj1;
obj1.var = ‘i’;

System.out.println(var1 + “, ” + var2);
System.out.print(obj1.var + “, ” + obj2.var);
}
