Which two settings must be defined in order to update a record of a junction object? Choose 2 answers

Read-only access on a relationship would prevent the user from making any changes to the links between the junction object and the primary parent record.

In order to modify the association between a junction object and its secondary parent record, the user must possess 'Read/Write access on the secondary relationship,' implying the necessary permissions to update the master-detail field on the junction object that links to the secondary master.

Updating a junction object record often involves changing its links to parent records. 'Read/Write access on the primary relationship' ensures the user has the required permissions to modify the master-detail field on the junction object that establishes the primary connection.

While Read/Write access on the junction object itself is necessary to update its non-relationship fields, the question focuses on the specific requirements related to its role as a junction, implying the critical need to manage both primary and secondary relationship fields, which B and C address more specifically.
