Final answer:
A rollback topper signifies a discounted price, indicating that the item's price has been lowered from its original amount.
Step-by-step explanation:
When a rollback topper is used on an item in a retail setting, it typically indicates that the item's price has been reduced from its original or previous price. Therefore, the correct answer is (a) Discounted price. A rollback topper does not necessarily mean that the item is on clearance, part of a seasonal promotion, or at full price. It specifically means the item has been marked down to a lower price that is intended to offer consumers a better deal or value.
