Final answer:
Artworks with two carved or painted panels are called diptychs, and with three, are called triptychs. So, the options are A and B.
Step-by-step explanation:
A diptych is a pair of linked panels often used in religious contexts and may feature intricate sculpted decoration. A triptych consists of a central panel flanked by two side wings, and such a format has a historical origin from Byzantine art.
An example is the Stavelot Triptych, a remarkable piece created in the mid-twelfth century consisting of a central panel with two enamels from Byzantine surrounded by wings containing fragments believed to be from the true cross. Similarly, The Merode Altarpiece is a triptych from the Northern Renaissance, showcasing connected panels with symbolic representations, very characteristic of the period's style.
Panel paintings are significant in the history of art and triptychs are a specific format within this category that artists have crafted meticulously to communicate religious and cultural narratives across different eras.
