An electronic marketplace is best described as:

• A. A seller-operated service with catalogs from vendors within a market
• B. A buyer-controlled procurement service
• C. A single-vendor catalog platform
• D. A consumer shopping portal

Answer: (A)

An electronic marketplace is a digital hub where multiple sellers participate and publish catalogs of their products within a market. The platform is typically operated by the marketplace provider, enabling buyers to browse across many vendors, compare offerings, and place orders in one place. This seller-operated, multi-vendor catalog setup distinguishes it from a buyer-controlled procurement service (where the buyer dictates catalogs and purchasing rules), a single-vendor catalog platform (which would only host one seller), or a consumer shopping portal (which targets individual shoppers rather than a business market).
