What is one of the Five Freedoms for animals in research?

The correct answer reflects one of the Five Freedoms, which are essential guidelines aimed at ensuring the welfare of animals in various situations, including research environments. The principle of being free from hunger or thirst emphasizes that animals should have access to adequate food and fresh water, which is fundamental to keeping them healthy and promoting their well-being.

This freedom is particularly important in a research setting where the well-being of animals can be affected by their living conditions, including their access to nutrition and hydration. Ensuring that animals are not deprived of these basic needs helps to minimize stress and maintain their health, which can also result in more reliable and valid research outcomes.

The other choices do not align with the established Five Freedoms framework. While concepts such as roaming freely, breeding, and interacting with visitors may be important for certain animal welfare considerations, they do not specifically relate to the core freedoms outlined to guide humane treatment of animals, especially in research contexts.
