Final answer:
The majority of e-business volume is Business-to-Business (B2B), driven by global connectivity and internet advancements that enable companies to transact with one another across borders.
Step-by-step explanation:
The vast majority of e-business volume is Business-to-Business (B2B). This is due to the vast improvements in communication technologies, like the internet, facilitating transactions and connections between buyers and suppliers globally. In business-to-business markets, companies engage in transactions with other companies, often in large volumes or bulk purchasing, which greatly exceeds the volume seen in business-to-consumer (B2C) or consumer-to-consumer (C2C) markets. This has intensified competition for many local retail businesses and opened up markets across borders, making B2B transactions a significant part of the global economy.
