Step 1: Understand the characteristics of a perfectly competitive market. These include many buyers and sellers, homogeneous products, free entry and exit, and firms being price takers.
Step 2: Identify the factors that specifically apply to firms in perfectly competitive markets. Price-taking behavior means firms accept the market price without influence.
Step 3: Recognize that free entry and exit allow firms to enter or leave the market without restrictions, which is a key feature of perfect competition.

Step 5: Compare these factors to the other options, which include elements like monopoly power, product differentiation, and collusion, none of which are characteristics of perfect competition.
