which helps enable an oligopoly to form within a market?\no costs of starting a competing business are too high.\no the government restricts market entry.\no the number of options in a market confuses consumers.\no no competition exists between producers.
Answer
Brief Explanations:
An oligopoly is a market structure with few firms. High start - up costs and government - restricted entry can limit new competitors, facilitating oligopoly formation. Confusing consumers doesn't directly enable oligopoly, and producers in an oligopoly do compete.
Answer:
Costs of starting a competing business are too high. The government restricts market entry.
