Bas-relief is a sculptural technique that combines the art of sculpture with architectural design. In later Roman houses, it was employed effectively to add depth and detail to wall surfaces, typically using materials like stucco. The method involves projecting figures or scenes from a flat background, allowing for a three-dimensional effect without fully detaching from the wall surface.

The correct answer highlights the practice of coloring raised stucco figures with gold leaf and incorporating mosaic work. This technique not only enhanced visual appeal but also conveyed cultural narratives and status through its elaborate designs. The use of gold leaf would create a striking contrast against the stucco, catching light and drawing attention to the artwork. Mosaic work often complemented these reliefs, providing intricate patterns or scenes that further adorned the walls.

In contrast, carving scenes into flat wood panels does not align with the traditional use of bas-relief in walls; painted murals are a different artistic approach; and applying fabric hangings would not utilize the bas-relief technique at all, as it does not involve three-dimensional sculptural elements. Understanding these distinctions clarifies why the use of colored raised stucco figures with gold leaf and mosaics was a prominent method in Roman interior decoration.
