How do you design a Pega application to meet this requirement?

A page application locally stores the same set of codes defied by an used within an external system of record. The Pega application does not locally store the associated to these codes. During case processing, the displayed labels for this set if codes are sourced from the external system of record. On any given data, the label associated to a code may change. You are asked to implement a report definition that display the current label associated to each code whenever the report is run.

How do you design a Pega application to meet this requirement?
A . Persist the most recently retrieved label for each code in a table. Join to that table when running the report.
B . Develop a SQL function rows that calls a stored procedure to retrieve the currently associated label for each code.
C . Display report definition rows using a custom section. Use a keyed-access Data page to source label values.
D . Query the distinct codes that the report would display. Develop an interface to retrieve the associated labels in bulk.

Answer: C
