What is printed besides the stack trace caused by the NullPointerException from line 16?

❌ A. AE
❌ B. AEBCD
✅ C. AEC
❌ D. AECD
❌ E. No output appears other than the stack trace

Explanation:
The main() method invokes go and A is printed on line 3. The stop method is invoked and E is printed on line 14. Line 16 throws a NullPointerException, so stop immediately ends and line 17 doesn’t execute. The exception isn’t caught in go, so the go method ends as well, but not before its finally block executes and C is printed on line 9. Because main() doesn’t catch the exception, the stack trace displays and no further output occurs, so AEC was the output printed before the stack trace.
