Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
process.join()
The join() method blocks the calling thread until the process whose join() method is called terminates.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
process.join()
Why this is correct
Join() is the correct method to synchronize process completion.
- ✗
process.wait()
Why it's wrong here
Process objects do not have a wait() method.
- ✗
process.terminate()
Why it's wrong here
Terminate() kills the process immediately, which is not a clean exit.
- ✗
process.close()
Why it's wrong here
Close() prevents further operations but does not wait for termination.
- ✗
process.is_alive()
Why it's wrong here
This only checks the status, it does not wait.
