Final answer:
A.Additional customers are most likely to expand a business in a global marketplace, as it directly increases sales volume and impacts revenue.
Step-by-step explanation:
In the context of a global marketplace, it can be argued that additional customers grow a business the most. Additional customers mean an increase in sales volume, which directly impacts the bottom line of a business and contributes to its growth. By leveraging improvements in communications technologies and the internet, businesses now have the capability to reach a global audience, providing scalability and increased competitiveness.
International trade also plays a pivotal role in business expansion. It allows even small economies to benefit from economies of scale, giving them access to a larger market, reducing costs per unit, and enhancing their competitive edge. Furthermore, international trade increases competition and the variety offered by several producers, which can lead to more innovation and better prices for consumers.
In the past decades, the interconnection between technology and globalization has revolutionized markets, as seen with the rise of business-to-business websites that connect suppliers and buyers globally. This digital marketplace can foster competitive pricing and sourcing opportunities. Therefore, while additional materials options and suppliers can aid in cost management and supply chain diversity, extending the customer base remains fundamental for significant business growth.
