Final answer:
Each feature matches with a type of Sales Transaction: expired status is linked to an Estimate/Quote, items not a mandatory field relates to an Opportunity, 'Pending Approval' is associated with a Sales Order, and an internal record purpose fits an Opportunity.
Step-by-step explanation:
In order to match each feature to the correct type of Sales Transaction, we consider a Sales Order, an Estimate/Quote, and an Opportunity as the three options.
- It can be of expired status - This typically applies to a B. Estimate/Quote, as these have an expiration date after which they are no longer valid.
- Items are not a mandatory field - This is often the case with a C. Opportunity, where the specifics of the sale may not yet be determined.
- It can have status "Pending Approval" - This status is usually associated with a A. Sales Order, which may require managerial approval before it is finalized.
- It is intended as an internal record - Again, this best matches an C. Opportunity, which is a record used by the sales team to track potential sales but is not a commitment like an Estimate/Quote or a Sales Order.
