Match the following :
`{:("COLUMN - I","COLUMN - II"),("A) Quartz","p) Three corners of "SiO_(4)^(4-)" tetrahedron are shared"),("B) Amorphous "SiO_(2),"q) Two corners of "SiO_(4)^(4-)" are shared"),("C) Sheet Silicates","r) All four corners of "SiO_(4)^(4-)" are shared"),("D) Cyclic silicates","s) Corners of "SiO_(4)^(4-)" are randomly linked"):}`

Answer

`A-r;B-s;C-p;D-q`

Explanation

Quartz - `Acl` 4 corners of `SiO_(4)^(-4)` are shared.
Amorphous `SiO_(2)` - corner of `SiO_(4)^(-4)` are randomly linked.
Sheet silicates - Three corners of `SiO_(4)^(-4)` tetrahedron are shared Cyclic silicates - `T_(100)` corners of `SiO_(4)^(-4)` are shared.
