Which of the following is true of the Toltecs?

b. They were the most powerful heir to Teotihuacan.

c. They ruled most of central Mexico for 400 years.

d. They were led by former members of the Zapotecs.

Let's go through the options:

a. They were the last great civilization that is part of the classical era.

- this is false! they were not the last civilization, as the Aztec came after that!

b. They were the most powerful heir to Teotihuacan.,

- we don't know that, as we don't actually know who the inhabitants of Teotihuacan are and what happened to them

c. They ruled most of central Mexico for 400 years. - this it the best answer!

d. They were led by former members of the Zapotecs - this could not be, as the Zapotecs actually outlived the Toltecs!
