Final answer:
Fair competition is the correct answer to the question and is the form that does not reduce competition, as opposed to price-fixing, market division, and tying arrangements, which are all forms of restraint of trade scrutinized under antitrust laws.
Step-by-step explanation:
All of the following are forms of restraint of trade that a company might use to reduce competition except: fair competition. Restraint of trade includes practices like price-fixing, market division, and tying arrangements. These practices are often scrutinized and regulated by antitrust laws because they can lead to reduced competition and consumer harm.
Price-fixing is an agreement between businesses to set prices at a certain level, which is illegal. Market division is a practice where competitors agree not to compete within certain areas or segments of the market. Tying arrangements are situations where a customer can only buy one product if they also purchase another product from the same company, which can be anti-competitive.
On the other hand, fair competition is encouraged and protected by antitrust laws. It is not a form of restraint of trade but rather the goal of these laws to ensure that businesses compete honestly and to the benefit of consumers. Therefore, fair competition is the correct answer to the question as it is the exception listed that does not reduce competition.
