B and C
The Mayans were polytheistic (worshiped multiple deities) so A is incorrect.
They had their own form of hieroglyphics so B is correct.
The practice of astrology was one of the most important aspects of Mayan culture, and they supplemented their knowledge of the stars using math to figure out complex patterns so C is correct.
It was the Incas, NOT the Mayans who had runners, so D is incorrect.
