Requirement:
* Allow users to choose options and define quantities during bundle configuration.
Configuration Types:
* None (A): Users can freely choose options and set quantities.
* Allowed (C): Users can choose options and optionally set quantities.
* Required (E): Users must configure the options and define quantities.
Why Other Options Are Incorrect:
* B: Configurable is not a valid value for the Configuration Type field.
