Answer:
A. The scientist will organize the layers by comparing the fossils and types of rocks.
Explanation:
A geologic column can be defined as a collection of rock layers that are typically grouped based on their relative ages in a descending order i.e from oldest to the youngest.
Generally, the layers of the rock that are found in various parts of the world are known to be different because they all comprises of distinct Earth's geological history.
In this scenario, a scientist wants to make a geologic column of rock layers from different parts of a state. Thus, the claim which best explains how the scientist will do this is that, the scientist will organize the layers by comparing the fossils and types of rocks.
Hence, the scientist will collect or gather the fossils obtained from various rocks located in different parts of the state and make a comparison.
