The correct answer is C. Geologist.
A geologist is a scientist who studies the solid Earth, the rocks of which it is composed, and the processes that shape it. Geologists seek to understand the composition, structure, history, and dynamics of the Earth and its surrounding space, and the processes that shape them. They use their knowledge to describe, understand, and predict changes in the Earth’s surface, and to assess the impact of these changes on human activity.
Meteorologists study the atmosphere and its phenomena. They are concerned with the weather, climate, and other atmospheric conditions.
Anthropologists study human beings and their societies. They are concerned with the origins, development, and diversity of human cultures.
Seismologists study earthquakes and other seismic activity. They are concerned with the causes of earthquakes, the propagation of seismic waves, and the effects of earthquakes on the Earth’s surface.
