What does the term "interment" refer to?

The term "interment" refers specifically to the act of placing human remains in a burial site, which is typically a cemetery. This definition encompasses the broader practice of burial, where the body is laid to rest in the ground. The term emphasizes the process of committing the remains to the earth, which is a traditional and longstanding method of honoring and memorializing deceased individuals.

In contrast to other options listed, interment does not refer to specific alternatives like mausoleums, columbariums, or niches, which are distinct forms of final disposition. While those options also involve the placement of remains, they are considered particular methods rather than the general practice that "interment" describes. Thus, the choice that aligns with the definition of interment appropriately identifies it as the placement of human remains in a cemetery.
