The correct answer is D. Create both customer and dealer as accounts, add each rep as a contact on the corresponding account and create an account hierarchy.

Universal Containers needs to represent separate business entities because separate bills are sent to each customer and each dealer. In Salesforce, business accounts are used to represent companies or organizations, and contacts represent the people who work for those accounts. Salesforce account hierarchies are used to show relationships between related accounts through the Parent Account field.

So the best model is:

Customer = Account

Dealer = Account

Representative at each business = Contact on that Account

Customer/dealer relationship = Account Hierarchy

A is incorrect because Account Teams represent internal Salesforce users working on an account, not external dealer/customer representatives.

B and C are incorrect because they do not correctly represent separate billing entities as separate Accounts.
