Which platform is an example of a digital sales channel?

The choice of Amazon as an example of a digital sales channel is correct because it operates entirely online, facilitating transactions over the internet. Digital sales channels are platforms that allow businesses to sell their products or services through digital means, often leveraging e-commerce capabilities. Amazon exemplifies this by providing a vast marketplace where consumers can browse, compare, and purchase products from various sellers.

In contrast, a local farmer's market, a retail outlet, and a business-to-business conference involve traditional, face-to-face interactions and sales processes. These venues require physical presence, limiting their ability to facilitate sales in the online space. Therefore, only Amazon fits the criteria of a digital sales channel, making it the best choice in this context.
