Public static int mystery (int firstNum, int secondNum)
{
FirstNum = firstNum * 2;
SecondNum = secondNum * 3;
Return firstNum + secondNum;
}
Public static void main(String[] args)
{
Int num1 = 10;
Int num2 = 11;
Int result = mystery(num1, num2) ;
}

A) num1 = 20, num2 = 33 and result is 53
B) num1 = 10, num2 = 11 and result is 53
C) num1 = 0, num2 = 0 and result is 0
