Universal Containers wants to create a report to show job applications with or without resumes.

The primary object of a custom report type is a fundamental design choice and cannot be changed after the report type is saved. Salesforce explicitly states in both the Enhanced and Legacy Custom Report Type Builder documentation that after saving a custom report type, the selected primary object cannot be changed. The primary object determines the base set of records represented by the report type and controls how additional related objects can subsequently be included. Consequently, the app builder must choose the Job Application object deliberately before saving the report type. Deployment does not permanently prevent a custom report type from being deleted, and the other options do not describe the core configuration limitation being tested. Therefore, B is the documented Platform App Builder consideration.
