What does "e-commerce" stand for?

E-commerce refers specifically to the buying and selling of goods or services over the internet. This encompasses a wide range of online business activities, including retail sales, electronic payments, online auctions, and internet banking. The rise of digital technology has enabled businesses to reach customers worldwide, allowing transactions to occur without the constraints of geographical boundaries. This definition highlights the primary function of e-commerce as a platform for online transactions, making it a crucial component of modern business practices.

The other choices focus on different aspects of business that do not align with the concept of e-commerce. For instance, the exchange of goods through physical stores pertains to traditional retailing methods and does not involve any online component. The analysis of business opportunities in various markets describes market research and strategy, which are essential for identifying potential markets but are not indicative of e-commerce. Creating physical retail locations refers to brick-and-mortar business setups, which contrasts with the digital framework of e-commerce. Therefore, the correct answer encapsulates the essence of e-commerce accurately.
