Answer: B dominant designs
Explanation:
The dominant design in a product class is, by definition, the one that wins the allegiance of the market place, the one that competitors and innovators must adhere to if they hope to command significant market. A dominant design is often the norm within the market which creates difficulties in other similar products to compete for market share. This often creates a monopoly over alternatives, whereby the only means of competing is to imitate or expand upon the concept.
