1. They cannot be created on any object.

2. They can only display the maximum value.

3. They can summarize data from a related list.

4. They can only count records, not summarize values.

For example, if you have a parent object like Account and related child records such as Opportunities, a roll-up summary field could summarize the total value of all Opportunities associated with that Account. This functionality enhances data analysis and reporting within the platform, making it easier for users to get insights without having to run complex reports or queries. Furthermore, roll-up summary fields only work with certain relationships (master-detail relationships) and cannot summarize data from related lists unless they are part of a master-detail relationship. The other options do not accurately describe the capabilities of roll-up summary fields. For instance, the first option implies a complete restriction that is not accurate as roll-up summary fields can indeed be created, but only under specific conditions. The limitation to displaying only the maximum value is overly restrictive, as roll
