Select the correct answer.


Answer explanation

  1. The conditional statement of the first if(a < b) returns true, because a is smaller than b. Therefore X is printed to the standard output.
  2. The conditional statement if(!bool == false) returns false, because the boolean variable bool is false.
  3. The condition if(a + b == 21) returns false because a + b = 8 + 12 = 20.
  4. The last if statement returns false. Therefore the else block is executed and the statement System.out.print(“Z”); writes the letter “Z” to the standard output.

So, the correct answer is d.
