The correct answer is C) the Olmecs.
The Zapotec and Toltec civilizations both featured ball courts, pyramids, and palaces that show evidence of the influence of the Olmecs.
The Zapotecs lived in the southern part of Mesoamerica, in the region of what today is the Mexican state of Oaxaca. They inhabited those lands from 500 BCE to 900 CE. Their capital city was the great Monte Alban, an impressive city full of building and temples, built at the top of a hill. The Toltecan civilization inhabited the central part of Mesoamerica, in what today is the state of Hidalgo, Mexico. Its most important city was Tula, close to the city of Tulancingo, Hidalgo Mexico. They lived there form the 10 to the 12th centuries and they also built ballcourts, palaces, and pyramids that show evidence of the influence of the Olmecs.
