Which term describes a private burial plot in ancient Rome?

The correct answer describes a specific aspect of Roman funerary practices. The term "ustrina" refers to a site designated for the cremation of the dead in ancient Rome. An ustrina could also refer to the actual cremation altar or pyre used during the cremation process, which was a common practice among Romans.

In contrast to burial plots, which might involve burial in a family tomb or a public cemetery, the ustrina is specifically associated with the act of cremation. This practice became prevalent especially in the late Republican and Imperial periods of Rome, reflecting a shift in cultural attitudes toward death and the afterlife.

Understanding the terminology and practices surrounding burials in ancient Rome provides insight into the societal norms and beliefs of the period, including the importance of respecting the dead and the rituals performed to ensure a proper journey to the afterlife. The other options presented refer to different aspects of funerary customs or ceremonies, but they do not specifically denote a private burial plot.
