Answer 2

A. era, period, epoch

Step-by-step explanation:

Geological time refers to the process of emergence, formation and transformation of planet Earth. Historical time, in turn, refers to the emergence of human civilizations and their capacity for written communication.

The periodization of the Earth is divided into Eons, these grouping the Eras, which group the Periods, which are divided into Epochs. If we look at the time scale represented, it is possible to note that the first eon, the Archean, lasted about two billion and one hundred million years, being the largest of all the temporal divisions of the Earth, because it was the period of formation of the planet until the appearance of the first forms of life.
