To determine what natural resource was used for the drawing, I would need to see the drawing or have more information about its characteristics. However, based on the options provided, here’s a brief overview:
- Clay: Typically used for sculpting or pottery, not drawing.
- Wax-based colored pencils: Made from a mix of pigments and wax, used for coloring.
- Graphite pencils: Composed of graphite and wood; used for sketching or drawing.
- Watercolors: Made from pigments suspended in a water-soluble binder, used for painting.
If you can provide details about the drawing’s medium or style, I could help deduce which natural resource was used.
