Final answer:
The analogy that best matches 'owner is to entrepreneur' is 'niche is to broad target', illustrating the similarity between the specialized roles of an entrepreneur and a niche in a market.
Step-by-step explanation:
An analogy that best fits the relationship of 'owner is to entrepreneur' is 'niche is to broad target' (d). This is because an owner has the same relationship to an entrepreneur as a niche has to a broad target market. An entrepreneur is someone who establishes and runs a business, taking on greater than normal financial risks in order to do so, similar to how an owner operates a business. Meanwhile, a niche market is a specific, focused portion of a market that a company can serve to differentiate itself from the competition, much like an entrepreneur carves out a unique path in the broader business landscape.
