What is the impact of mobile commerce in retail?

The impact of mobile commerce in retail primarily enhances the convenience for shoppers, making option B the most accurate choice. Mobile commerce allows consumers to shop anytime and anywhere via their mobile devices, which simplifies the shopping process. Customers can quickly browse products, make purchases, and receive services without being tied to a physical location or specific store hours. This convenience is a significant factor driving the growth of mobile commerce, as it aligns with the modern consumer's demand for flexibility and efficiency in their shopping experience.

While the other options may reflect secondary effects of mobile commerce, they do not capture the primary impact as effectively. For instance, while mobile commerce can heighten competition among retailers by allowing for easier price comparisons and access to more choices, this is a broader industry phenomenon and not as directly tied to the shopping experience itself. The reduction in the need for physical stores and the limited use of traditional advertising are more indirect outcomes of the rise of digital shopping environments and consumer behaviors rather than the fundamental impact of mobile commerce.
