Answer:
Letter D is correct. Extreme value retailers.
Explanation:
Extreme value retailers are those whose focus is on offering customers very low prices. This type of consumer price pass-through can be guaranteed by the strategy of such retailers that reduce advertising costs and other marketing variables, and purchase their supplies from ideal suppliers who already sell at lower market prices.
They are therefore able to achieve price advantages by marketing non-durable goods, which are those that are made to be consumed immediately and constantly.
