• A. The atrium is the central social hub; the tablinum, cubicula, and triclinium cluster around it, with a peristyle garden beyond.
• B. The tablinum is the central social hub, with other rooms around it.
• C. The cubicula form the central social hub, with the atrium as a side space.
• D. The peristyle garden is the central social hub.

Answer: (A)

The central social hub in a Roman domus is the atrium. This main reception space sits at the heart of the house, where guests were greeted and daily business was conducted. The rooms that support and flank this hub—such as the tablinum, the cubicula, and the triclinium—are arranged around the atrium to facilitate movement between reception, private rooms, and dining. The tablinum serves as the family office or front-facing reception area for clients, the cubicula are the sleeping rooms, and the triclinium is the dining space for entertaining. Beyond these is the peristyle garden, a later, open courtyard reached through the house but not the central focus itself. This layout emphasizes the atrium as the living, social core of the domus.
