Let us test each option against what we actually know about glass.
Option A, crystalline solid: a true crystalline solid, such as common salt or quartz, has particles arranged in a fixed repeating three dimensional pattern and melts sharply at one fixed temperature. Ordinary glass does none of this, it softens gradually over a temperature range, so this option does not fit.
Option B, super cooled liquid: glass forms when molten silica based material is cooled so quickly that the molecules get frozen in a random, liquid like arrangement before they can line up into a crystal lattice. This disordered internal structure, combined with solid like rigidity at room temperature, is exactly the definition of a super cooled liquid, also called an amorphous solid. This fits glass perfectly.
Option C, condensed gas: this phrase does not correspond to any recognised description of glass, gases condense to liquids, not to rigid amorphous solids like glass, so it is not applicable here.
Option D, liquid crystal: liquid crystals are a special mesophase shown only by certain elongated organic molecules that keep some directional order while flowing like a liquid. Ordinary window or bottle glass made of silicates shows no such molecular alignment, so this option is wrong too.
By elimination and by definition, option B, super cooled liquid, correctly describes the state of glass.
