Answer

Answer:

A. Costs of starting a competing business are too high., B. The government restricts market entry.

Brief Explanations:

High start - up costs and government - imposed entry restrictions are barriers to entry that can enable oligopolies. High costs deter new entrants, and government restrictions limit competition, allowing a few firms to dominate the market. Confusing consumers and lack of producer competition are not typical factors for oligopoly formation.
