Answer: AB

Explanation:

Whenever possible, you will want to use EDTs and EDTs should be created for each atomic entity in the situation that your application is modeling. You should only create subtypes when they are needed. In other words, when you are creating an EDT that extends another EDT, but you aren’t changing any of its properties, you probably do not need to create a new subtype.
