Solution

The correct answer is a.(0, n). This is because an order can have zero to many parts. There may be orders that do not include any parts (for example, if an order is cancelled or if it's a service order), and there may be orders that include multiple parts. Therefore, the participation of Part in the 'has' relationship with Order is optional and can be multiple, hence the (0, n) notation.
