Prior to API version 44.0, to cache data returned from an Apex method, you had to call setStorable() in JavaScript code on every action that called the Apex method. For API version of 44.0 or higher, you must mark the Apex method as storable (cacheable) and you can get rid of any setStorable() calls in JavaScript code. The Apex annotation approach is better because it centralizes your caching notation for a method in the Apex class. https://developer.salesforce.com/docs/atlas.en-us.lightning.meta/lightning/controllers_server_apex_auraenabled_annotation.htm

"To cache data returned from an Apex method for any component with an API version of 44.0 or later, annotate the Apex method with @AuraEnabled(cacheable=true)." So why not D?
