Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use the 'onvalue' parameter.
Why it's wrong here
onvalue defines the value assigned when checked, not the tracking mechanism.
- ✓
Pass a BooleanVar object to the 'variable' parameter.
Why this is correct
Variable objects allow for dynamic tracking of widget values.
- ✗
Use the state attribute directly.
Why it's wrong here
The state attribute is for widget status, not variable binding.
- ✗
Use the 'command' parameter to set a global flag.
Why it's wrong here
While possible, it is not the recommended way to track state compared to using a variable.
