Given: public class Test1 { static void doubling (Integer ref, int pv) { ref =20; pv = 20; } public static void main(String[] args) { Integer iObj = new Integer(10); int iVar = 10; doubling(iObj++, iV

The correct answer is A. 11, 11. The codedoubling(iObj++, iVar++);increases both variables from to 10 to 11.
