C. Create an extension of the CustTable table and add the new field there.
D. Duplicate the CustTable table and add the new field to the duplicate.
Answer
C. Create an extension of the CustTable table and add the new field there.
Explanation
The correct way to add a new field without modifying the original CustTable table is to create an extension of the CustTable table and add the new field there (Option C). Directly adding the new field to the CustTable table (Option A) is incorrect as it involves direct modification of the original table, which is not recommended. Creating a new table with the new field and associating it with the CustTable table (Option B) is not the correct approach because it adds unnecessary complexity to the data model. Duplicating the CustTable table and adding the new field to the duplicate (Option D) is also incorrect as this practice can lead to data integrity issues.
