The correct answer is option 1: vitrified liquid. Glass is a vitrified liquid, which means that it has the properties of both a liquid and a solid. Unlike crystalline materials, glass does not have a regular internal structure. Instead, the atoms or molecules in glass are arranged in a disordered or amorphous manner, giving it a unique structure.

Option 2: crystalline material is incorrect. Unlike crystalline materials, glass does not have a repeating arrangement of atoms or molecules.

Option 3: semisolid is incorrect. While glass is similar in appearance to a solid, it does not have a fixed shape or structure like a traditional solid material.

Option 4: polymeric material is incorrect. Glass is not a polymer, which is a type of material composed of long chains of repeating units.

In summary, glass is a vitrified liquid due to its disordered atomic or molecular arrangement, distinguishing it from crystalline materials, solids with fixed shapes, and polymeric materials.
