Final answer:
The answer is A) Obelisk, a tall stone monument that tapers to a pyramidal point, historically used in ancient Egypt and often inscribed with hieroglyphics.
Step-by-step explanation:
This description closely matches the structure of an obelisk, which is used as a monument. These structures are made from a single piece of stone and often have inscriptions and carvings. In contrast, the other terms provided have different characteristics. A menhir is a single large upright monolith, a ziggurat is a terraced step pyramid that supports a temple, typically found in ancient Mesopotamia, and a stele is a stone or wooden slab, generally taller than it is wide, that is erected for funerary or commemorative purposes, often inscribed with text or with relief carving.
Obelisks were significant in ancient Egyptian culture and often stood at the entrance to temples. They are still recognizable landmarks in modern times, sometimes having been transported to different locations around the world.
