Universal Containers (UC) is in the process of migrating legacy inventory data from an enterprise resource planning (ERP) system into Sales Cloud with the following requirements:
1. Legacy inventory data will be stored in a custom child object called Inventory__c.
2. Inventory data should be related to the standard Account object.
3. The Inventory__c object should inherit the same sharing rules as the Account object.
4. Anytime an Account record is deleted in Salesforce. the related Inventory__c record(s) should be deleted as well.
What type of relationship field should a data architect recommend in this scenario?
