Chadwick's report stated that cemeteries must be __________.

Chadwick's report emphasized the necessity for cemeteries to be municipalized, which means that they should be operated and managed by local government authorities rather than by private entities or organizations. This shift was proposed to address issues related to public health and urban planning during the 19th century, where unregulated cemetery practices were leading to unsanitary conditions and overcrowding.

Municipalizing cemeteries allows for greater oversight, the establishment of regulations and standards, and ensures that burials and memorial practices align with community needs and health standards. This concept also supports the idea of public access and responsibility for cemetery maintenance and management, ultimately benefiting public health and the environment.

The other choices, while they might suggest various forms of cemetery management or action, do not align with the intent and findings of Chadwick's report, which specifically advocated for the establishment of cemeteries as public entities under municipal control.
