The most accurate comparison of the political characteristics of the Mayan and Inca Empires would be:
Rulers in the Mayan Empire demonstrated political power by commissioning intricate sculptures. Rulers in the Incan Empire demonstrated political power by strictly controlling who could wear certain garments.
This response effectively highlights the ways in which political power was expressed in both empires: the Mayans through artistic commissions that showcased their rulers' importance and the Incas through social control, particularly in terms of clothing, which reflected status and authority.
