Correct answer: 4
The correct answer is 4. Trace: 1. P0 (i=0): Forks. Parent (P0) breaks, prints (1). Child (C1) continues. 2. C1 (i=1): Forks. Parent (C1) breaks, prints (2). Child (C2) continues. 3. C2 (i=2): Forks. Parent (C2) breaks, prints (3). Child (C3) continues. 4. C3 (i=3): Loop condition (3 < 3) is false. Loop terminates. C3 prints (4). Total executions: 4.
