Final answer:
Amorphous solids are typically formed by large neutral molecules that due to their size and complex structure do not arrange in a regular geometric pattern. The well-known example of an amorphous substance is glass. The correct option is 'C'.
Step-by-step explanation:
Amorphous solids typically form from large neutral molecules. These types of substances lack the long-range order that is seen with crystalline solids. Due to their large size and complex structure, they fail to arrange in a regular geometric pattern, thereby resulting in an amorphous structure. An example of a substance that forms an amorphous solid is glass, which is composed of large silicon dioxide molecules.
