What is a benefit of extending an existing table such as Task when creating a new application?

• A. Use Existing Fields With No Modifications
• B. Existing Logic From the Parent Table Will Be Automatically Applied
• C. New Fields Must Be Created
• D. Requires Additional Maintenance

Answer: (B)

Extending an existing table means the new table becomes a child of the parent, so it automatically inherits its fields and behavior. The big win is that the logic defined on the parent—such as business rules, ACLs, UI policies, and client scripts—applies to the child table without re-creating them. This delivers consistent behavior across records and reduces duplication and maintenance, since you don’t have to rewrite the same logic for the new application. You can still add fields specific to your app or adjust rules as needed, but the core logic from the parent is already in place. Other options describe scenarios that aren’t guaranteed benefits of table extension, and they don’t capture the efficiency and consistency gained by inheritance.
