Answer: C. Use buffer stocks to ensure speedy supply.

Explanation: All options except the use of buffer stocks to ensure speedy supply are included in the differentiation strategy decisions. A differentiation strategy is one of the ways a business distinguishes itself from competition and is defined as the approach in development of new products that a firm employs in order to offer unique products that customers will find superior to others in the market. It is important because it allows businesses not just to distinguish themselves from competition, but to also emphasize the unique aspects that make its product superior, accelerating visibility and perceived expertise, that results in better growth and profitability.
