Correct answers are B, D
Global picklist:
This creates a single list of values that can be used across different objects (like Accounts and Cases), guaranteeing consistency.
Dependent picklist:
This allows the values displayed in a picklist to be dependent on the selection made in another field. In this case, "Dream House Realty" could set up the Category picklist to show different options depending on whether the record is an Account or a Case.


Custom picklist:
While custom picklists allow for creating unique lists of values, they don't inherently provide consistency across objects or offer dependent relationships.
