Which one of the following constitutes a valid reason/condition for a company to consider shifting away from pursuit of a differentiation strategy keyed to assembling and selling top-quality entry-level cameras at premium prices?
A. When one or more rival companies are spending above-average amounts on advertising in all 4 geographic regions--trying to overcome the advertising advantage they have would be virtually impossible
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
C. When selling a large volume of entry-level cameras is much more important to achieving a high image rating than is producing and marketing entry-level cameras having a high P/Q rating (4-stars and above)
D. When a big fraction of companies in the industry are having more than 1 sales promotion campaign each quarter
E. When the volume of sales that a high-end differentiator can achieve is too small to enable the company to increase the warranty period beyond 90 days?
