What does the term "animal ethics" encompass?

The term "animal ethics" encompasses the moral considerations regarding the treatment and use of animals. This field of study examines the rights and welfare of animals, the ethical implications of using animals for various purposes such as companionship, research, food, and entertainment, and the responsibilities humans have toward animals. It addresses questions about what is right and wrong in the way animals are treated, encouraging consideration of their well-being and intrinsic value.

While the other options pertain to specific practices related to animal care or management, they do not capture the broader philosophical and moral discussions central to animal ethics. For example, rules governing breeding practices or regulations related to transport focus on logistical and operational standards rather than ethical considerations. Similarly, dietary needs are important for animal health and management but do not inherently involve moral or ethical discussions about how animals should be treated. Therefore, option B is the most accurate representation of what animal ethics encompasses.
