   A developer is writing a test for a trigger that enforces a business rule: an Opportunity cannot be inserted unless its related Account has a certain custom field set to 'Active'. The developer wants to test both the success and failure scenarios. Which approach is best?

   • AUse @testSetup to create an Account with the field set to 'Active' and then change it in the failure test.
   • BUse Test.loadData to load two Accounts, one active and one inactive.
   • CCreate one Account with the field set to 'Active' and use it for both tests, expecting the failure test to fail.
   • DCreate a Test Data Factory that creates an Account with the field set to 'Active' for the success test, and a separate factory method that creates an Account with the field set to 'Inactive' for the failure test.
