Which best explains why large companies have advantages over smaller companies?

Large companies often benefit from economies of scale, allowing them to produce goods at a lower cost per unit due to higher production volumes. They also have greater access to capital, enabling them to invest in research, marketing, and technology more effectively than smaller firms. Additionally, larger companies can leverage brand recognition and established customer bases, which enhances their competitive positioning in the market. These factors combined create barriers for smaller companies, making it challenging for them to compete.
