What does the master record determine in a master-detail relationship?

1. Visibility of dependent fields

2. Ownership and sharing settings

3. Field types available

4. Data exporting capabilities

The correct answer is: Ownership and sharing settings

In a master-detail relationship within Salesforce, the master record plays a crucial role in determining ownership and sharing settings of the detail record. The master record is the parent in this relationship, which means that it controls several aspects of the child record, including how it is shared and who can access it. When a detail record is created, it inherits the ownership and sharing settings from its master record. This means that if the master record's owner is changed, the ownership of all child records will also change to reflect that. Additionally, the sharing settings apply to child records based on the master record's settings. This structure provides a level of data control and security, ensuring that only those who have access to the master record also have access to its details. Understanding this dynamic is essential for properly structuring data relationships in Salesforce, as it affects how records interact with one another within the platform.
