After written notice of the authorizing agent not picking up remains after __________ days, the crematory can dispose of remains.

The correct answer indicates that after 90 days from the written notice provided to the authorizing agent about not picking up the remains, the crematory is allowed to dispose of them. This timeframe is established to balance the rights of the family with the operational needs of the crematory.

Under Arizona law, it is essential for crematories to handle unclaimed remains in a timely manner to maintain public health and safety. The 90-day period offers ample opportunity for the authorizing agent to make arrangements for the remains while also allowing the crematory to maintain its business operations effectively.

This timeframe helps prevent indefinite delays and ensures that the facilities do not become burdened with remains that are not claimed. Other options, such as 60 days, 120 days, or 150 days, do not align with the legal standards set forth in Arizona, which clarifies the responsibilities of both the crematory and the authorizing agent regarding unclaimed remains.
