Final answer:
In merging two cases, you can select which case to merge into another case, effectively choosing a primary and secondary case. Setting a parent case may also be an option, while assigning the case owner and indicating master fields are generally not part of this process.
Step-by-step explanation:
When you plan to combine two cases using the merge case process in a customer relationship management (CRM) system, one option that you can specify is C. Select which case to merge into another case. This involves choosing one case to act as the primary case and merging the other case into it. The primary case retains its identity, and information from the secondary case is incorporated into it. Another option you might have is A. Set a parent case, allowing you to organize cases hierarchically. However, options B and D, which are assigning the case owner and indicating which fields should be set as the master field from each case record, are not typically part of the standard merge case functionality. Instead, case ownership and field values are usually predetermined by the configuration of the CRM system.
