A Public Sector Organization (PSO) would like to enhance its publicly available website, built in Experience Cloud, to allow constituents to report their concerns about someone's health or safety. The PSO is already using Public Sector Solutions. The requirement from the PSO is that the constituent should be able to report their concerns both as authenticated users and anonymously. Additionally, internal staff should be able to separately track their investigations and any follow-up in a separate Case. Leveraging Public Sector Solutions functionality, what configuration should the Technical Consultant use to meet the requirements?

A. Use the Complaint Case and Case objects.

B. Use record types on Case, one for the constituents and one for internal staff

C. Use the Public Complaint and Case objects.

D. Use a custom object for the Complaint with a lookup relationship to Case.
