What characterizes free-range farming?

Free-range farming is characterized by allowing animals the opportunity to roam freely outdoors for at least part of the day. This practice focuses on the welfare of the animals, enabling them to engage in natural behaviors such as foraging, grazing, and socializing with other animals. Access to outdoor spaces is often considered essential for promoting the health and well-being of livestock, as it reduces stress and encourages physical activity.

The other options do not align with the principles of free-range farming. For instance, keeping animals indoors at all times contradicts the very essence of free-range systems, which prioritize outdoor access. Feeding organic feed is a separate agricultural practice that may or may not be part of free-range farming; it is not a defining characteristic. Similarly, raising animals without any human interaction does not reflect the principles of free-range farming, which can involve responsible human care and management in conjunction with animal welfare. Thus, the correct choice highlights the fundamental aspect of free-range farming that differentiates it from other farming practices.
