Businesses that operate predominantly online, such as Amazon, eBay, Yahoo!, and Google; they differ from retailers with physical stores.

• A. online presence
• B. B2B
• C. e-tailers
• D. batch production

Answer: (C)

The idea being tested is the sales channel and how a retailer primarily reaches customers. Businesses that sell mainly online are e-tailers, retailers that operate over the internet through websites or online marketplaces to process orders and payments. This fits examples like Amazon and eBay, which rely on digital platforms rather than physical shopfronts. Online presence would just mean having a website, not necessarily selling most of their product online. B2B refers to selling to other businesses, not the online versus offline channel. Batch production is about how goods are manufactured, not how they’re sold.
