Final answer:
The correct answer to the description provided is a Tholos tomb, specifically known from the Mycenaean civilization, characterized by its beehive shape, dromos entrance, and corbeled vaulting.
Step-by-step explanation:
The tomb described in the question is a Tholos, which is option C. A Tholos is a beehive-shaped tomb from the Aegean civilization, known for its corbeled vaulting that creates an expansive open space. Notably, the Treasury of Atreus at Mycenae is a prime example of a Tholos tomb. These tombs feature a dromos, or a narrow passageway, leading to a post-and-lintel doorway topped by a relieving triangle. The distinct architectural style includes a corbeled vault which is often monumental in scale, and Mycenaean architecture in general reflects their warring society.
The tomb is approached by a dromos and features a long corridor with side chambers and corbelled vault. Moreover, Tholos tombs were covered by a tumulus or a mound of earth to mark the grave. The interiors were intricately decorated, mirroring the luxurious aspects of Mycenaean culture and sometimes containing grave goods, as in the Treasury of Atreus.
