Why each option

The question asks for the correct definition of an Apex method wired to a Lightning component property, specifically for `searchResults` storing a list of Opportunities.

A@AuraEnabled(cacheable=true)Correct

For an Apex method to be wired to a Lightning Web Component property, it must be decorated with the `@AuraEnabled(cacheable=true)` annotation, enabling client-side caching and proper functioning with the wire service. (The complete definition also requires `public static` and the correct return type and parameters).

B@AuraEnabled(cacheable=true) public List<Opportunity> search(String term)

This definition is missing the `static` keyword, which is a mandatory requirement for Apex methods that are invoked from Lightning Web Components via the wire service.

C@AuraEnabled(cacheable=false) public static List<Opportunity> search(String term)

While the method includes the `static` keyword, the `cacheable=false` attribute is not recommended for methods used by wired properties as it prevents client-side caching and can negatively impact component performance.

D@AuraEnabled(cacheable=false) public List<Opportunity> search(String term)

This definition is incorrect as it lacks the `static` keyword, which is mandatory, and specifies `cacheable=false`, which prevents the method from being effectively used by a wired property for cached data retrieval.

Concept tested: Apex @AuraEnabled(cacheable=true) for LWC wired properties
