Periodically, the dimensions of the containers change. Frequently, the database users require the volume of a container. The volume of a container is calculated based on information in the shape and size tables.

You need to hide the details of the calculation so that the volume can be easily accessed in a SELECT query with the rest of the container information. What should you do?

A. Create a user-defined function that requires ContainerID as an argument and returns the volume of the container.

B. Create a stored procedure that requires ContainerID as an argument and returns the volume of the container.

C. Add a column named volume to the container table. Create a trigger that calculates and stores volume in this column when a new container is inserted into the table.

D. Add a computed column to the container table that calculates the volume of the container.
