The correct answer is letter C.

When sandpaper is made, an abrasive material is bonded to a papaer backing. The product quality depends on the quality of the principal raw material, of grit and paper and how uniformly and securely they can be combined.

Even with good glue, the paper used in early sandpaper fell apart when wet so that it could only be used in very dry and dust operations.

Back in the 1920's with the growing of the automobile industry, a great amount of sandpaper was needed to finish the paint on auto bodies and the dust was causing lead poisoning to the workers.
