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
✓
Mark the property as @track and reference it in a reactive wire property or function.

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Call the wire adapter imperatively inside a JavaScript function.
Why it's wrong here
Wire adapters are reactive and automatically update when reactive properties change.
- ✓
Mark the property as @track and reference it in a reactive wire property or function.
Why this is correct
Reactive properties in wire arguments cause the wire to re-provision data when changed.
- ✗
Use standard hidden HTML inputs to store state.
Why it's wrong here
Not a recommended pattern in LWC.
- ✗
Reload the entire browser page using window.location.reload().
Why it's wrong here
Reloading the page destroys component state unnecessarily.
