Final answer:
An amorphous solid is a state of matter in which the particles have nearly zero attraction to each other, resulting in a randomly arranged structure. Examples include glass and some plastics.
Step-by-step explanation:
The correct answer is d. amorphous solid.
In an amorphous solid, the particles have nearly zero attraction to each other. This means that they are randomly arranged and don't have a definite repeating pattern like in crystalline solids. Examples of amorphous solids include glass and some plastics.
Unlike liquids and gases, amorphous solids maintain their shape and volume.
