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 @api track decorator on the Apex method call inside the template.
Why it's wrong here
Incorrect because @api track is not used for calling Apex methods.
- ✗
Use the @wire decorator on an imported Apex method and update a reactive property.
Why it's wrong here
Incorrect because @wire is used for reactive, automatic provisioning of data, not imperative invocation.
- ✗
Configure the component metadata file to fetch the data imperatively on load.
Why it's wrong here
Incorrect because metadata configuration does not determine whether data is fetched imperatively.
- ✓
Call the imported Apex method as a JavaScript function inside the button's event handler and handle the returned promise.
Why this is correct
Correct because imperative Apex is called as a function returning a promise inside an event handler.
