The Correct Option is C
Solution and Explanation
The following solids are formed by $X,\, Y,\, Q$ and $Z$.
$X Y_{2},\, X_{2} Z,\, Q Z$ According to the above formulae,
$X, Y, Q$, and $Z$ exhibit $+2,-1,+4$, and $-4$ oxidation states respectively. Therefore, the formula of the compound formed by $Q$ and $Y$ is $Q Y_{4}$.
$X Y_{2},\, X_{2} Z,\, Q Z$ According to the above formulae,
$X, Y, Q$, and $Z$ exhibit $+2,-1,+4$, and $-4$ oxidation states respectively. Therefore, the formula of the compound formed by $Q$ and $Y$ is $Q Y_{4}$.

Properties of Solids
Properties of Solids:
- In solids, particles are tightly or closely packed.
- Solids are incompressible, meaning the constituent particle is arranged close to each other and because of that, there is negligible space between the constituent particle.
- Solids are rigid, due to lack of space between the constituent particles which make it rigid or fixed.
- Solids have definite mass, volume and shape due to which it has a compact arrangement of constituent particles.
- The intermolecular distance between molecules is short.
- The rate of diffusion in solids is very low.
