Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Assign to a global variable
Why it's wrong here
This is not thread-safe and not the intended way to handle context management.
- ✗
Use the return statement
Why it's wrong here
Returning from a context manager function terminates the execution.

Why this is correct
Yielding passes control to the block inside the with statement and provides the value.

Raise an exception
Why it's wrong here
Raising an exception interrupts the context flow.
