The correct answer is A because Case_Issue__c is described as a junction object. In Salesforce, a junction object is typically built with two master-detail relationships to model a many-to-many relationship.

Salesforce documentation states that sharing access to a junction object record is determined by the user’s sharing access to both associated master records and the sharing setting on the relationship fields.

So, for auditing users to view Case_Issue__c records, they need read access to both parent/master records: Case and Issue__c.

Why others are incorrect:

B misses access to Issue__c.

C includes only the junction object and misses both parent/master records.

D misses access to Case.
