What is a notable characteristic of Mayan art?

Mayan art is distinguished by its remarkable architectural achievements, particularly noted for step pyramids that are richly adorned with elaborate relief sculptures and intricate hieroglyphics. These pyramids serve not just as religious temples but also as platforms for ceremonies and astronomical observations. The relief sculptures and hieroglyphics convey stories, historical events, and religious beliefs, highlighting the sophistication and complexity of Mayan culture.

In contrast, while painted murals are indeed a part of Mayan artistry, they do not encompass the full breadth of the Mayan artistic tradition, which includes significant architectural structures. The other options describe characteristics that either miss the essence of Mayan art or oversimplify it by suggesting a limited focus on certain media, ignoring the extensive and multifaceted nature of their cultural expressions.
