Which of the following is an example of value-added agriculture?

Value-added agriculture refers to the process of transforming raw agricultural products into products that have a higher value in the market, thereby generating more profit for the producer. The correct answer highlights a farm that markets a "farm branded" cheese, which is an effective illustration of value-added agriculture.

By creating and selling cheese under a unique brand, the farm is not just selling the raw milk but adding additional processing, marketing, and branding that enhances the product's value. This process can lead to increased consumer recognition, potential price premiums, and a differentiated product in the marketplace.

In contrast, farms that sell raw milk, use organic feed, or simply raise dairy cows do not inherently undergo this transformation or enhancement of their products. These activities do not necessarily increase the market value of the product in the way that processing and branding a cheese product does. Thus, focusing on creating distinct products from basic ingredients exemplifies the essence of value-added agriculture.
