Answer: Option (a) is the correct answer.
Explanation:
Amorphous means without any crystalline structure or definite shape. Whereas a solid whose atoms are not bonded together in a definite lattice pattern. This solid is non-crystalline in nature.
For example, glass, gel, plastic etc are all amorphous solids.
Whereas solid sulfur, solid calcium, and gold have a definite lattice pattern and has a crystalline structure. Thus, they are not amorphous solids.
Thus, we can conclude that out of the given options glass is most likely to be amorphous.
