The term "lithograph" is derived from which material?

The term "lithograph" originates from the Greek words "lithos," meaning stone, and "grapho," meaning to write or draw. This relates directly to the method of lithography, which traditionally involves creating images on a flat stone surface. The process utilizes the natural hydrophilic properties of the stone, allowing for the production of prints by applying ink to the areas that have been treated. This technique became popular in the late 18th century and is significant in printmaking history. The other materials listed do not directly relate to the original process of lithography, making stone the correct answer.
