Final answer:
A lithologic well-log provides information on the composition of rock cuttings and is used to create detailed stratigraphic columns for understanding subsurface geology.
Step-by-step explanation:
A lithologic well-log describes the visual recording of the rock and soil formations encountered in the borehole or well, usually through the analysis of samples of those rocks and soils. Among the options provided, option B) Provides information on the composition of rock cuttings best describes what a lithologic well-log embodies. Lithologic well-logs are essential for understanding the stratigraphy and composition of subsurface geology. They help geologists to specify the different stratigraphic units present by analyzing rock fragments or cuttings brought to the surface during drilling. These rock samples are examined and described in terms of their lithology to create detailed stratigraphic columns, which graphically represent the sequence of strata.
