A Salesforce Administrator at a financial services firm is designing a custom data model to track Loan Applications (Loan_Application__c) and associated Underwriting Reviews (Underwriting_Review__c). Management has specified the following key requirements:
1. Deleting a Loan Application record must automatically delete all associated Underwriting Review records.
2. A summary field on the Loan Application record must automatically calculate the total number of linked Underwriting Review records.
3. User access permissions to an Underwriting Review record must be inherited directly from its parent Loan Application record.
Which relationship type should the administrator create on the Underwriting_Review__c object to meet these business requirements?
- A Master-Detail relationship field referencing Loan_Application__cAnswer
- BA Lookup relationship field referencing Loan_Application__c with a native Roll-Up Summary field configured on Loan_Application__c
- CA Lookup relationship field referencing Loan_Application__c with custom record-level sharing rules configured for security inheritance
- DA Many-to-Many junction relationship connecting Loan_Application__c and Underwriting_Review__c via a secondary custom object
