Final answer:
The more difficult it is to enter an industry, the higher the barriers to entry. These barriers can be due to various factors, including government regulations, control of resources, and economies of scale.
Step-by-step explanation:
The correct answer to the question is: c) More; higher. This is because the more difficult it is for an organization to enter an industry as a new competitor, the higher the barriers to entry are. Barriers to entry can take many forms, such as government-enforced regulations, capital requirements, brand identity, and economies of scale. For example, a city passing a law limiting the number of licenses for taxicabs creates a government-enforced barrier to entry, while owning a unique natural resource like a spring with very pure water can be a natural barrier to entry. An industry where economies of scale are significant in relation to market demand is an example of a structural barrier to entry, as it can discourage new entrants due to the high costs involved in starting a business in such an industry.
