The two field types that are specialized versions of the Query field type are:
A. Data reference:
This field type is used to reference data from an external source dynamically. It allows the application to pull in data as needed without storing it directly within the case.
D. Case reference:
This field type is used to reference another case within the Pega application. It is useful for linking related cases and managing dependencies between them.
