Answer 2

The correct answer is option(A) Cenozoic.

In the timeline of Earth, The Cenozoic era occurred about 66 million years ago. During this period, the Earth began drying and cooling up and the Glaciations were at the peak.

This age has four divisions. In the last division, Quaternary, there were about 4 glaciation periods and this period was marked by ice ages. Moreover, Homo sapiens evolved during this period.

Note that Paleozoic age was a period of continuous glaciation. In this question, periodic glaciation is asked, so the answer will be Cenozoic.
