A Master-Detail Relationship has several defining traits:5
* Roll-up Summaries: This relationship is the only one that allows the Master record to summarize data (sum, count, min, max) from its Detail records (Option C).
* Object Types: The Master can be either a standard object (like Account) or a custom object (Option D).
* Ownership and Security: The Detail record inherits its owner from the Master record, and as such, there is no " Owner " field on the Detail record (Option E). Additionally, the detail record ' s security and sharing settings are inherited from the master, meaning permissions are not independent (negating Option B).
Option A is incorrect because an object can only have a maximum of two master-detail relationships.
