What type of silicate minerals is shown from this arrangement of silicon tetrahedron?

Since no choices are given, I would just give the 6 possible tetrahedron structures of silicate minerals. Then, it will be up to you to distinguish which one fits to your choices.

1. Isolated tetrahedra - they are separated by positive charges. An example would be olivine.

2. Ringed tetrahedra - they are linked together by positive charges, like that of tourmaline.

3. Tetrahedra - oxygen is shared by two neighbors like that of the pyroxene family.

4. Double chains/Ribbons - example whould be the amphibole family

5. Silica Sheets - when oxygen is shared by three adjacent molecules like the micas and the clay minerals.

6. Three-dimensional framework - four oxygen atoms are linked to other tetrahedra like feldspar and quartz.
