Geologists are primarily concerned with the study of rocks and the Earth's crust, and therefore would most likely collect rock and soil samples from the lithosphere. The biosphere refers to living organisms, the atmosphere to the air and gases surrounding the Earth, and the hydrosphere to water bodies on the planet, so these options are not as relevant to the study of rocks and soil.
