Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The first if condition (x==4) && !b2 evaluates to false, so line 18 is skipped. Line 19 is not inside any block, so it prints 2. The second if condition performs an assignment b2 = true which evaluates to true, and since b1 is true, line 21 executes and prints 3.
