Answer:
Step-by-step explanation:
Enabling Data Protection and Privacy in a Salesforce org will add the Individual object to the org. To track data privacy information for individuals, the Individual field needs to be added to the page layouts of the objects that relate to individuals.
Therefore, the page layouts that should have the Individual field added to track data privacy information will depend on the specific objects in the Universal Containers org that relate to individuals. The Salesforce admin for Universal Containers will need to determine which objects these are and add the Individual field to their page layouts as needed.
