Hint: Carbon and silicon both belong to the same block and same group. They belong to \[p\]-block and IV A group. As we are moving from top to bottom in a group the electronegativity of the atoms decreases. The difference of electronegativity will allow the formation of the compound.

Complete step by step answer:
* We know that \[SiC\] is called a silicon carbide. Means in\[SiC\], silicon is positively charged and carbon is negatively charged.
* As moving from top to bottom in a group the electronegativity of the atoms decreases. So, the carbon is having a little bit more electronegativity than the silicon.
* So, the carbon will take the electrons from silicon and form\[SiC\].
* Now coming to options, in option A, it is mentioned that silicon carbon, it is wrong.
* In Option B, Quartz. Quartz means silicon dioxide (\[Si{{O}_{2}}\]), then option B is wrong.
* In option D, Silicon carboxylate. In \[SiC\], there is no carboxyl group. So option D is wrong.
* Coming to option C, Carborundum. The other name of \[SiC\]is carborundum.
* Silicon carbide (\[SiC\]) is covalent solid which is a subtype of crystalline solid.
* It is covalent solid since the atoms of silicon are connected with carbon through covalent bonds tetrahedrally.
So, the correct option is C.

Note: Don’t be confused with the words, Silicon Carbon and Silicon carbide. There is no chemical that exists with the name of silicon carbon. Silicon carbide has the formula \[SiC\].
