Hello! Number one is D, they were called Moros. Number two is B, even though there were two civilizations, the Inca (Peru) and the Mapuche (Chile). Number three is C, think of the Peninsula de Yucatán which is in Mexico, that is where the Aztecas lived (Mexico). Number four is A, even though the majority of the Maya were in Guatemala (the majority of Mexico used to be a part of Guatemala). I hope this helps!
The first one is b, they are both b actually
It can be anything! But I think there was a text before this question.
