Final answer:
The feathered serpent, known as Quetzalcoatl, is frequently depicted in Aztec sculpture, as indicated by temple motifs and artifacts found in museums. The correct option is A.
Step-by-step explanation:
In Aztec sculpture, the feathered serpent is frequently depicted. This is evidenced by various historical references, such as the great Temple of the Feathered Serpent in Teotihuacan, the depiction of Quetzalcoatl—the Plumed Serpent god—in various cultures of Mesoamerica, and the presence of serpent motifs in Aztec pottery and temple decorations.
For example, Quetzalcoatl, which means "Feathered Serpent," was one of the most important gods in the Aztec pantheon, as seen in the figure from the National Museum of Anthropology in Mexico. The representation of serpents in sculpture is also highlighted in descriptions of temple facades adorned with figures like Xiuhcoatl, the fire deity serpent.
