Which objects does Super User Access apply to?

Super User Access is specifically designed to provide broader visibility and control over certain records within the Experience Cloud ecosystem. This access is particularly relevant for custom objects, as it allows designated users to manage and interact with these records effectively.

Custom objects are tailored to meet specific business needs beyond what standard objects can provide. By allowing Super User Access for custom objects, organizations can ensure that key users have the capabilities needed to oversee these specialized records, which can involve unique data, processes, or workflows.

While standard objects such as cases, leads, and opportunities are fundamental to Salesforce's operation, the focus of Super User Access is primarily on enhancing functionality and management of custom records tailored for specific applications or business cases. Hence, the best understanding of Super User Access is that it applies to custom objects, thereby making option B the most appropriate choice.
