For ceremonial objects, the Aztecs and Maya used:​

A) ​emeralds, rubies, and gold
B) ​copper, silver, and gold
C) ​silver, gold, and lapis lazuli
D) ​silver, gold, and bronze

The Aztecs and Maya used copper, silver, and gold for their ceremonial objects. They were skilled in metalworking and created intricate designs that were highly valued. While precious stones like emeralds and rubies were also used in their art, they were not as commonly utilized as metals. Lapis lazuli is not a material found in Mesoamerica, so it is not likely to have been used in their objects. Bronze was not commonly used by the Aztecs and Maya, who focused on precious metals.
