In what situations is embalming legally required?

Embalming is legally required in specific situations, primarily when the deceased is to be displayed in viewings or open casket services. This process is crucial for preserving the body, enhancing its appearance, and allowing for public visitation, which is a common practice in many funeral services. When families request viewings or a traditional service where the deceased is present, embalming is typically necessary to ensure that the remains are handled with dignity and respect, while also adhering to public health standards.

Other scenarios, such as cremation or direct burial, do not necessarily require embalming, as these arrangements often do not involve public viewings. Therefore, the requirement for embalming is primarily based on the nature of the service and the family's wishes regarding how they wish to honor their loved one. In summary, embalming becomes legally mandated in the context of specific arrangements or services that involve the deceased being viewed by others, which makes option C the correct choice.
