You are configuring a matrix report that shows workers' average base pay by job profile.

TheLookup Related Valuefunction retrieves a value from a related business object. Since Compensation Group is not stored directly on the Worker object but instead through theJob Profilebusiness object, this function lets you traverse the relationship to return the related field into your report.

From Workday Reporting documentation:

“Lookup Related Value – Returns a field from a related business object. Use this to bring data from associated objects into a report when the field is not directly available on the primary object.”

Therefore, the correct answer isC. Lookup Related Value.
