Hint: This is a branch of geology. Geology explains the Earth's composition on its surface and under its surface, and its mechanisms. This also includes the means to assess and identify the relative and absolute ages of rocks located in a given area.

Complete answer:
Geology is a study of the Earth, which deals with the solid Earth, its minerals, and the mechanisms by which it varies in time. The analysis of the solid substances of a natural satellite or terrestrial planet like the Moon or Mars will also include geology. Modern geology significantly correlates with all other sciences of the earth, including hydrology and air science, and is thus considered one important component of Earth system interconnected science and planetary science.
Tectonics are the processes which control the structure, property and evolution of the earth's crust over time.
Seismology is a study into vibrations and earthquakes that pass across and around the globe. A seismologist is an earthquake and seismic wave scientist.
Mineralogy is a branch of geological study interested in chemical analyses, crystal-structures, and mineral and mineralized objects' physical properties. Mineral origin and composition processes, mineral classifications, geographical distribution and use of these minerals are basic studies performed within minerals.
Petrology is the geological division which studies the rocks and their conditions. Three divisions occur in petrology: igneous, metamorphic and sedimentary petrology.

Hence, the correct answer is option (D)

Note: Seismology is a study into vibrations and earthquakes that pass across and around the globe. Mineralogy is a branch of geological study interested in chemical analyses, crystal-structures, and mineral and mineralized objects' physical properties. Petrology is the geological division which studies the rocks and their conditions.
