What is an online marketplace?

An online marketplace functions as a digital platform that facilitates transactions between buyers and sellers for various goods and services. This type of marketplace allows various vendors to list their products or services, and buyers can browse through these offerings, comparing features, prices, and options. The transactions might involve direct purchases or negotiations, enhancing convenience for consumers looking to find a wide range of products in one place.

While other options describe elements that can exist in the online space, they do not encompass the full definition of an online marketplace. A site that only lists product prices lacks the key element of facilitating transactions between buyers and sellers. A platform for exchanging services among users is a narrower concept that may not include tangible goods. Similarly, a website focused solely on user reviews does not involve the transactional aspect that is essential to an online marketplace. Overall, option B accurately captures the essence of what an online marketplace represents, highlighting its role as a vital connector in e-commerce.
