era
Of the options provided, the longest division of the geologic time is an "Era."
To determine this answer, you can draw upon your understanding of geologic time divisions or refer to reliable sources such as textbooks, scientific articles, or geological websites.
In geology, time is divided into different intervals for a better understanding of Earth's history. The largest division is called an "Eon," followed by "Era," "Period," and finally "Epoch."
An "Eon" can span billions of years, and it is further divided into smaller "Eras," which can cover hundreds of millions of years. "Periods" divide an era into tens of millions of years, and "Epochs" break down periods to durations of millions of years.
Remember that geologic time divisions are relative and not uniformly defined. Different sources may use slightly different terminology or subdivision boundaries, but the general framework remains consistent.
