Which property mode is appropriate for collecting multiple telephone numbers from a user?

The correct choice for collecting multiple telephone numbers from a user is Page List. This property mode is specifically designed to handle collections of items. When you need to gather multiple pieces of data of the same type—in this case, telephone numbers—a Page List allows you to store each number as a separate entry within a single structure, making it easy to manage and process.

A Page List creates an indexed collection of pages, where each page can contain the same properties, such as different telephone numbers. This structure is beneficial when the system needs to iterate over the collection, extract individual numbers, or perform operations on them collectively.

In contrast, while Value Group could also be used for collecting multiple values, it is not as suitable when structured data is required. Value Groups are generally better for simple, flat data without the need for complex organization. A Single Value mode can only store one value at a time, making it unsuitable for collecting multiple telephone numbers. A Page mode, while allowing for complex structures, is not optimized for the same kind of indexed collection that a Page List provides for multiple instances of the same type of data.
