"UC sells a bundle with multiple options.

 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.

D: Disabled prevents any configuration, which contradicts the requirement.

 Salesforce CPQ Reference:

Configuration Types are documented under Bundle Configuration Guidelines ​.
