Anonymous Apex allows developers to execute ad hoc code snippets without creating a permanent class or trigger. It is useful for tasks like bulk data manipulation or testing.
* B. Deleting 15,000 inactive Accounts:
* Anonymous Apex can perform ad hoc bulk operations to clean up data after a deployment.
* Example:
Use Cases:List<Account> inactiveAccounts = [SELECT Id FROM Account WHERE IsActive__c = false LIMIT 15000]; delete inactiveAccounts;
* C. Running a batch Apex class:
* Anonymous Apex can execute batch jobs for data processing.
* Example:
apex
Copy code
Database.executeBatch(new UpdateContactBatch());
* A. Schedule an Apex class to run periodically: This requires a scheduled job, not Anonymous Apex.
* D. Add unit test code coverage: Unit tests must be written in test classes and cannot be added using Anonymous Apex.

* Why These Settings?
* bubbles: true: Enables the event to propagate up the containment hierarchy.
* composed: true: Allows the event to cross the Shadow DOM boundary.
* Why Not Other Options?
* Other combinations (e.g., bubbles: false) prevent the event from propagating or crossing the Shadow DOM boundary.
