Which of the following types of animals are included under the term "assistance animals"?

The term "assistance animals" refers to animals that provide support to individuals with disabilities, which can include a wide range of species, not limited to any particular type. The Americans with Disabilities Act (ADA) primarily recognizes dogs as service animals, but the broader definition used in other contexts, such as in housing under the Fair Housing Act, encompasses a variety of animals that assist individuals with disabilities.

Under this broader context, assistance animals can include not only dogs but also other animals, such as cats and in some cases even birds, if they provide necessary support for the individual's well-being. This definition emphasizes the role of the animal in mitigating the person's disability rather than restricting the type of animal based solely on species.

Therefore, the correct answer reflects the understanding that many types of animals can serve as assistance animals, as long as they provide a benefit to a person with a disability, thus highlighting the inclusive nature of the term in supporting diverse needs.
