Answer:
C) They depict Maya religious beliefs
Explanation:
Sao Bartolo is the oldest Mayan site that is found so far. It is not a big site, but it is very important because it has multiple well preserved mural paintings that depict the religious beliefs of the Maya. The oldest ones are traced back to the third century BC. The murals are very obviously heavily influenced by the Olmec culture, and it is well known that the Maya culture used the Olmec culture as its basis. The site is located in the northern part of Guatemala, and apart from the murals it has several interesting relatively well preserved architectural structures. The Aztecs never managed to get hold of this territory, but even if they did they would have not destroyed it as their culture is largely based on the Mayan one, especially when it came to religion. The only real threats to the site were the natural conditions and the Spanish conquistadors.
