About `95%` of the earth's crust is composed of silicate minerals, alumino silicate clay r silica. Silicates are classified on the basis of bonding and the metal ions present in them. Some of the common categories of silicates are
(I) orthosilicates , (II) pyrosilicates
(III) cyclic silicates , (IV) chain silicates
(V) amphiboles , (VI) sheet silicates
(VII) three-dimensional network silicates
Which of the following is not true regarding cyclic silicates ?

A

Its general formula `(SiO_(3))_(n)^(2n-)`

B

It has two shared oxygen per tetrahedron

C

Both `Ca_(3)[Si_(3)O_(9)]` and `Be_(3)al_(2)[Si_(6)O_(18)]` are cyclic silicates

D

Pyroxene is a chain silicate but do not contain cyclic structure
