use case

Use case: Sell goodsDescription: Accept tender from a customer, package products being purchased, and remove the products from inventory.
Actors: Clerk
Preconditions: Customer has chosen products to buy from inventory.
Postconditions: Products are no longer in inventory. Store cash balance is increased.
1. The clerk scans the product codes on each item being purchased.
2. As each item is scanned, the system calculates a running total, prints line items on a receipt, and displays the line items to the clerk on the ReceiptPanel.
3. The clerk can remove items from the purchase by pressing the "Void item" button.
4. ?
5. Once the customer has paid for the items, the items are removed from inventory and the cash register balance is incremented by the total amount of the good sold.

What is wrong with above usecase?
a)There are design details intermixed with the requirements.
b)The actor's actions and system responses are not separated.
c)"Sell goods" is too broad to be a use case.
d)There is nothing wrong with this use case.

I believe it's a. Any other correct answers with explanations?
