What are "cremains"?

Cremains refers specifically to the ashes that remain after a body has been cremated. During the cremation process, the body is exposed to high temperatures, resulting in the reduction of organic material and elements, ultimately leaving behind a fine powdery substance. These ashes can then be collected and given to the deceased's family, typically stored in an urn or scattered in a meaningful location.

The other options do not align with the definition of cremains. For instance, the traditional burial clothes relate to the garments worn by the deceased prior to burial, which is entirely separate from the cremation process. A memorial garden is a dedicated space for remembrance but does not entail the ashes themselves. Lastly, referring to funeral service providers does not connect to the concept of ashes or remains following cremation. Therefore, the only accurate definition in the context of the question is that cremains refer to the ashes remaining after the cremation process.
