Which of the following is a key aspect of maintaining competition in markets, as per the role of the FTC?

The emphasis on preventing unfair business practices is central to the Federal Trade Commission's (FTC) mission to maintain competition in markets. By focusing on this aspect, the FTC aims to create a level playing field where businesses can compete fairly without the influence of deceptive or abusive tactics that can harm competitors and consumers.

Preventing unfair business practices helps ensure that no single company can gain an undue advantage over others through fraud, coercion, or monopoly tactics. This not only fosters a vibrant market environment where innovation can thrive but also protects consumers from exploitation and ensures they have access to various choices at fair prices.

In contrast, maintaining high product prices goes against the principles of competition, as it would reduce consumer choice and limit market dynamics. Subsidizing small businesses is generally outside the FTC's purview, focusing more on promoting competition than financial assistance. Regulating the flow of international trade pertains to trade policy and is typically managed by other agencies rather than the FTC's core mission regarding competition.
