Ivahew [28]

Answer:

A) Phanerozoic

Explanation:

In the given question, the chart about the evolution of insects has not been provided but based on the previous knowledge, this question can be answered.

The geologists have divided the time scale into many variables in which Eon represent the longest time scale period which has lasted for the millions of year.
