Answer:
The correct answer would be C, Marginal Benefits.
Step-by-step explanation:
The point at which it is no longer advantageous to buy in bulk is known as the Marginal benefit. If a company buys material or product in bulk, there is always a benefit associated with it in buying the material or product in the large quantities, because if a product or material is bought in bulk, the unit cost of that material or product decreases which results in the benefit of the company. But there is a point where it is no longer beneficial for the company to buy that in bulk, because there will be no advantage of buying another unit of that material or product, this point is called as the Marginal Benefit.
