* Why WITH SECURITY_ENFORCED?
* Ensures field-level security and sharing rules are enforced in SOQL queries.
* Prevents unauthorized records or fields from being accessed or displayed.
* Why Not Other Options?
* B and C: with sharing and inherited sharing enforce record-level access but do not handle field- level security.
* D: without sharing ignores sharing rules, which would display all records regardless of user permissions.
