The correct answer is A. In a market where buyers are uncertain of a​ product's quality, a firm that signals the quality of its product can charge a higher price. Since guarantees and warranties are more costly for​ low-quality producers than​ high-quality producers, only​ high-quality producers will offer them.

This is because a seller can use signals such as guarantee or warranty to convey to the buyers that their product is of high quality. This helps to reduce the uncertainty of the buyers and provides them with assurance. However, offering guarantees and warranties can be costly for low-quality producers, as they may have to bear the costs of repairing or replacing defective products. Therefore, only high-quality producers, who are confident in the quality of their products, are likely to offer such guarantees and warranties. As a result, buyers perceive these signals as an indication of quality, which allows the seller to charge a higher price.
