Quiz question - Introduction to Data Modeling

In module 5, 'introduction to data modeling' topic, there is a question quite difficult to understand the correct answer:

The data model for a financial services application indicates a one-to-many (1:n) relationship between the data object that represents the customer and the data object that represents their accounts, and must support an arbitrary number of accounts of each type. The best implementation for the Accounts data object would be a ____________. (Choose One)
This type of relationship cannot be modeled.
Page
Page Group
Page List

Since the relationship is 1:N and there is a word 'arbitrary' seems that the answer should be 'page group' cause there is no need to order the accounts, is that correct? The answer on quiz is 'page list' but I really don't understand why, is there anyone available to clarify and help with it?
