Using the following business rules for a centralized contact management database select the correct specialization hierarchy symbol on the diagram below.

Each contact will be assigned a unique number.

We need to store name, address, telephone, and email address for everybody.

A contact may be a vendor, someone we purchase items from. We need to remember our credit limit and a remit to address.

A contact may also be a customer. We need to store their favorite color, so that we can recommend items to them, and their ship-to address.

We may also keep contact information about individuals who are neither a customer or a vendor.

Some contacts are both a customer and a vendor.
