After a design review, a member of the development staff asks you to add a new column named CommissionRate to the Product table.

You add the new column. You need to configure the table to assign the default value as efficiently as possible. What should you do?()

A. Create an INSERT trigger to assign the default value to each item in the table.
B. Create a CHECK constraint to validate the data and to assign the default value to each item in the table.
