c or the 3rd option however u would like to put it
Cathedral definition. A Christian church building in which a bishop has his official seat (cathedral is Latin for “chair”). A cathedral is usually large and imposing, and many cathedrals are important in the history of architecture. (See Chartres, Notre Dame de Paris, and Saint Paul's Cathedral.)

Metaphors are figures of speech in which, something is referred to, but not directly.
