B is definitely the correct answer. The model shows that a customer and an order can have a one-to-many or many-to-one relationship, but never a one-to-one or a many-to-many relationship. This is basic database design stuff, folks!

I agree, B is the correct answer. It's all about the one-to-many relationship between Customer and Order.

Hmm, this is a tricky one. I was initially leaning towards D, but then I realized that an order must be placed by at least one customer. A and B seem to be the most logical options here.

But what about option A? An order may be placed by many customers. That could also be a valid business rule.

I think the correct answer is B. A customer may place many orders. The entity relationship model clearly shows that the relationship between Customer and Order is 'many-to-many', meaning a customer can have multiple orders and an order can be placed by multiple customers.
