Answer:

The answer is C. Molds and casts.

Explanation:

Because if you think of it, you have sand and you draw something with your finger, it leaves an imprint. Right? Then if you filled that imprint with cement it would make a CAST of the "drawing" you made in the sand. So the inicial drawing was a cast or mold for the "fossil" or drawing you made.

Does that make sense? lol

Hope this helped!
