Product cardinality controls which of the following?

Product cardinality within Salesforce Industries CPQ controls aspects related to product configuration quantities, specifically:

Is optional (A): This controls whether a product must be included in a configuration or if it can be optionally chosen by the customer.

Has a default quantity of 2 (D): This sets a predefined quantity for the product when it is added to a configuration, streamlining the process and ensuring consistency for standard orders.

These controls are crucial for defining how products are presented and managed within the CPQ process, influencing both the user experience and the internal logic of product configurations.
