Which type of disposition involves the cremation of remains?

Cremation is distinctly characterized as the process of reducing the body to its basic elements through the application of intense heat. This method of disposition transforms the remains into ashes, commonly referred to as cremains, which can be handled or memorialized in a variety of ways afterward. In contrast, burial involves placing the body in the ground, entombment refers to interment within a crypt or mausoleum, and green burial emphasizes an environmentally sustainable approach to body disposal without the use of chemicals or non-biodegradable materials. Therefore, cremation is the only option among those listed that specifically denotes the process of reducing remains by fire.
