Amorphous material is characterized by by a) organized crystalline structure; b) high hardness and ductility c)the chaotic arrangement of atoms or high hardness; d) excellent magnetic, electrical properties, atomic chaotic layout, high hardness.

C.The chaotic arrangement of atoms or high hardness

Explanation:

We know that atomic arrangement in Solids are of two types

 1)Crystalline

 2)Amorphous

Crystalline arrangement have periodic arrangement where as Amorphous arrangement have random arrangement.

Generally all metal have Crystalline arrangement and material like wood ,glass have  random arrangement ,that is why wood and glass is called Amorphous.We know that wood act as a insulator for conductivity and glass is a brittle and hard material.

So from above we can say that Amorphous material have chaotic arrangement of atoms or have high harness,so our option c is right.

the warning light flashes for a second or two when the engine starts. if it stays on, there's must be something wrong with the coolant. you should never dare to continue driving when the light is on. pull over as soon as possible and shut the engine off.
