What is a cella in the context of a temple?

A cella is the inner sanctum or shrine room of a temple, typically where the cult deity's statue is housed and where offerings are made. In many ancient temples, the cella serves as the most sacred space, directly associated with the worship practices and rituals that occurred within the structure. It is generally surrounded by walls and may have limited access, underscoring its importance as the focal point of worship.

The other options, while they describe areas that can be found in or around temples, do not characterize the cella. The waiting area for worshippers is not the central shrine; the storage area for offerings would be separate from the sacred space; and the courtyard is an external area, not part of the inner sanctum intended for direct worship. Thus, the correct choice emphasizes the cella's role as the core religious space within a temple.
