Define E-Commerce.

• A. The activity of buying or selling products online
• B. Advertising a business or product using the internet
• C. Managing supply chains digitally
• D. Selling only physical goods in a shop

Answer: (A)

E-commerce is about completing business transactions over electronic networks, primarily the internet. It involves customers buying and selling goods or services online, usually including online payments, order processing, and delivery or access to the product.

The best answer captures this core action: transactions conducted over the internet. The other options describe related activities that aren’t the defining feature of e-commerce—online advertising is marketing, digital supply chain management is about coordinating information and goods flows, and selling only physical goods in a shop describes traditional, non-online retail.
