Answer:
B: It could be carved at the base of a stone column
D: It represented the creator god Kukulcán.
The Maya feathered serpent figure was commonly depicted at the base of stone columns and represented the deity Kukulcán, who was associated with creation, fertility, and water. The figure was typically depicted with a serpent's body and feathered wings and could have been seen as a symbol of the heavens. It was not necessarily meant to welcome visitors, and its style was not necessarily realistic.
