What is needed to create "with" or "without* reports on the new custom object?
A . Row-Level Formula
B . Report Bucket Field
C . Report Filters
D . Custom Report Type

Answer: D

Explanation:

To create “with” or “without” reports on the new custom object, a custom report type is needed. A custom report type defines the relationship between one or more standard or custom objects for reporting purposes. It allows users to select which fields they want to display in their reports and filter by related objects.
