Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Wait for the function to return.
Why it's wrong here
You must explicitly fetch the result.
- ✗
Use the join() method on the pool.
Why it's wrong here
Join() is for processes, not result retrieval.
- ✗
Pass a callback function.
Why it's wrong here
While callbacks work, get() is the primary way to retrieve results.
- ✓
Call the get() method on the returned object.
Why this is correct
Get() retrieves the result of the asynchronous task.
- ✗
Check the pool's result list.
Why it's wrong here
There is no such list.
