Which term means buying and selling through the internet via devices such as a computer or smartphone?

• A. E-Commerce
• B. Pure Play
• C. Concierge
• D. Amenity

Answer: (A)

Electronic commerce is the practice of buying and selling goods and services over the internet using devices such as a computer or smartphone. It encompasses online storefronts, shopping carts, digital payments, and order fulfillment, enabling transactions to happen remotely. That makes it the clearest match for describing the online buying and selling process.

The other terms don’t fit as well. A pure play business operates exclusively online, which is a specific model within e-commerce rather than the act of buying and selling itself. A concierge refers to personalized assistance or service, not online trade. An amenity is a feature that adds comfort or convenience, not a method of commerce.
