Answer: Option (a) is the correct answer.
Step-by-step explanation:
A substance that is made from sand and is transparent in color that is heated with chemicals is known as glass.
Water is a natural resource that is made up of two hydrogen molecules and one oxygen atom. Molecular formula of water is
.
When water freezes then it changes into ice, that is, liquid state of water changes into solid state upon freezing.
On the other hand, when freezing of atmospheric vapor occurs then it results into ice crystals known as snow.
Therefore, we can conclude that out of the given options glass is least like the others.
