Match List - I with List - II.

Choose the correct answer from the options given below:

Correct option is C

Explanation:
Each silicate mineral is classified based on how the silicate tetrahedra (SiO₄) are linked:
· Augite belongs to the pyroxene group, which has single chain silicate structures → (A)-(II).
· Hornblende is part of the amphibole group with double chain silicate structures → (B)-(I).
· Biotite is a mica mineral with sheet (phyllosilicate) structure → (C)-(IV).
· Quartz has a three-dimensional network (tectosilicate) structure → (D)-(III).
Information Booster:
Silicate structures form the backbone of most rock-forming minerals:
· Single chain silicates: Each tetrahedron shares two oxygen atoms.
· Double chain silicates: Alternate tetrahedra share two and three oxygen atoms.
· Sheet silicates: Each tetrahedron shares three oxygen atoms forming sheets.
· Framework silicates: All four oxygen atoms are shared forming a 3D network.
