Explanation

Three true characteristics of Salesforce master-detail relationships: (C) Roll-up summary fields are supported, allowing the master record to aggregate data-count, sum, min, max-from related detail records. (D) The master object can be a standard or custom object. (E) The detail record's owner is inherited from the master record; detail records do not have an independent owner field. Option A is false-each object supports a maximum of two master-detail relationships, not five. Option B is false-detail record permissions are controlled by the master record, not set independently; this is a defining characteristic of master-detail (as opposed to lookup relationships).
