Answer:
B. Quantity discount
Explanation:
Quantity discount can be referred to a strategy for enticing customers to make more purchases for an item being offered at a cheaper price per unit for bulk purchases.
In simple terms, a seller reduces the price per unit for an item, if a buyer is buying a certain bulk quantity of that item.
For example, if a pack of snacks is sold at $5 per unit for 1 purchase, the seller can decide to give incentive to customers in the form of quantity discount by proposing that anyone making a purchase of more than 5 units would pay $3 per unit instead if $5 per unit for 1 pack.
This is what is called quantity discount.
