A principal difference between a red ocean and a blue ocean is:
A. A red ocean exists in a stagnant industry whereas a blue ocean originates in a growing industry
B. Powerful brands are unlikely to exist in a red ocean
C. Products offered in a blue ocean are not necessarily of superior quality, but more attuned to customer needs than those offered in a red ocean
D. Any industry can become a red ocean over time, but blue oceans can be created in only a limited number of industries
Explanation: The passage emphasizes that a blue ocean strategy focuses on "value innovation" and finding unmet customer needs, rather than competing solely on superior quality (which is often a red ocean strategy). The passage states that blue oceans can be created in **any** industry (not a limited number), and brands **are** built in blue oceans.
