In a relational database that includes a 'Customers' table and an 'Orders' table, where each order is linked to a customer through a 'CustomerID', which of the following scenarios could potentially violate referential integrity and lead to database anomalies?

Updating a 'CustomerID' in the 'Customers' table without cascading changes to the 'Orders' table.

Adding a new order to the 'Orders' table with a 'CustomerlD' that does not exist in the 'Customers' table.

All of the above

Deleting a record from the 'Customers' table without checking if there are related orders in the 'Orders' table.
