What is referred to as "mobile commerce"?

Mobile commerce, often abbreviated as m-commerce, specifically refers to the buying and selling of products or services through mobile devices, such as smartphones and tablets. This term encompasses all aspects of e-commerce that take place in a mobile environment, allowing consumers to make purchases, access information, and conduct transactions while on the go. As the usage of mobile devices continues to rise, mobile commerce has become increasingly important for businesses seeking to meet consumer demands.

The other options, while relevant to technology and online business, do not accurately represent mobile commerce. For example, conducting market research through APIs relates more to data collection and analysis rather than the actual transaction process. Creating mobile applications for businesses focuses on software development, which, while important for enabling mobile commerce, does not define the commerce aspect itself. Managing online databases pertains to data storage and organization, which is a backend function that supports online transactions but is not directly related to the buying and selling process via mobile devices. Thus, choice B clearly captures the essence of mobile commerce.
