Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The 'Allow reparenting' option was not checked on the master-detail relationship field.
By default, master-detail relationships do not allow reparenting once a child record is created unless the 'Allow reparenting' setting is enabled on the field definition.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The External ID field on the parent object is missing.
Why it's wrong here
External IDs affect upsert operations, not master-detail parent linkage rules.
- ✗
The child record is owned by a queue instead of a user.
Why it's wrong here
Ownership has no bearing on master-detail reparenting restrictions.
- ✓
The 'Allow reparenting' option was not checked on the master-detail relationship field.
Why this is correct
If 'Allow reparenting' is unchecked, child records cannot be moved to a different parent record after creation.
- ✗
Data Loader is attempting to insert child records before parent records.
Why it's wrong here
Inserting children before parents results in a missing parent ID error, not a reparenting error.
