Final answer:
Reducing barriers to entry is not a form of business competition; businesses often seek to maintain or increase barriers to prevent new competition, contrary to innovating, cutting costs, and advertising which are competitive strategies.
Step-by-step explanation:
Among the forms of business competition, reducing barriers to entry does not typically represent a form of competition utilized by businesses. Instead, reducing barriers to entry is counterintuitive for a firm that wants to maintain a competitive advantage. Firms often seek out ways to make it harder, not easier, for competitors to enter the market. Forms of competition such as innovating, cutting costs, and advertising offer ways for businesses to outperform competitors, attract more customers, and gain market share. Barriers to entry include legal restrictions, control of resources, and intellectual property protection, which are all methods to maintain a competitive edge or even create a monopoly.
