Final answer:
A broad differentiation strategy is generally not well-suited when there are many ways to differentiate a product or service and buyers perceive these differences as valuable, or when technological change is rapid and competition revolves around evolving product features.
Step-by-step explanation:
In which of the following market circumstances is a broad differentiation strategy generally NOT well-suited? A broad differentiation strategy is generally not well-suited when there are many ways to differentiate a product or service and many buyers perceive these differences valuable, as stated in option D. This is because when there are already numerous ways for a product or service to stand out in the market, it becomes difficult for a company to effectively differentiate itself from competitors.
Similarly, a broad differentiation strategy may not be well-suited when technological change is fast-paced and competition revolves around rapidly evolving product features, as mentioned in option E. In such circumstances, maintaining a unique differentiation can be challenging due to the constant changes in technology and evolving customer preferences.
