Which term refers to the retailing of goods online?

• A. Online Retailing
• B. Market
• C. E-commerce
• D. Consumer Panels

Answer: (C)

E-commerce refers to buying and selling goods and services over electronic systems, especially the Internet. It covers all kinds of online trading, including selling directly to consumers, selling between businesses, and even online marketplaces, along with the payment and delivery processes that make those transactions possible. That breadth is what makes it the best answer here: it describes the entire online trading activity, not just a specific way of selling. Online retailing is a precise description of selling to customers online, but e-commerce is the broader, standard term used in business contexts. The other options don’t fit because a market is the place or system for trade, consumer panels are groups used for market research, and while online retailing fits the idea of selling online, it’s narrower than the term e-commerce.
