Answer:
Step-by-step explanation:
B. When there are so many companies trying to sell top-quality, premium-priced entry-level cameras that it is very difficult for any one company to capture an appealingly profitable market share.
The valid reason/condition for a company to consider shifting away from the pursuit of a differentiation strategy keyed to assembling and selling top-quality entry-level cameras at premium prices is option B - "When there are so many companies trying to sell top-quality, premium-priced entry-level cameras that it is very difficult for any one company to capture an appealingly profitable market share."
If too many competitors offer similar products in the market, it becomes challenging for a company to maintain a high market share and charge a premium price. In such a situation, companies may need to consider changing their strategy to remain competitive and profitable. This may involve offering a different product or service, targeting a different market segment, or adopting a different pricing strategy.
