Anton created a chart listing different types of materials.

Types of Materials

\begin{tabular}{|l|l|}
\hline \multicolumn{1}{|c|}{ Type } & \multicolumn{1}{c|}{ Example } \\
\hline conductor & silver \\
\hline insulator & [tex]$X$[/tex] \\
\hline semiconductor & [tex]$Y$[/tex] \\
\hline superconductor & mercury \\
\hline
\end{tabular}

Which best completes the chart?

A. [tex]$X$[/tex]: copper, [tex]$Y$[/tex]: glass

B. [tex]$X$[/tex]: rubber, [tex]$Y$[/tex]: copper

C. [tex]$X$[/tex]: paper, [tex]$Y$[/tex]: silicon

D. [tex]$X$[/tex]: silicon, [tex]$Y$[/tex]: glass

To complete the chart, we need to match the materials to their appropriate categories: conductor, insulator, semiconductor, and superconductor.

Given:
1. Conductor -> Silver
2. Insulator -> [tex]$X$[/tex]
3. Semiconductor -> [tex]$Y$[/tex]
4. Superconductor -> Mercury

We evaluate the options for [tex]$X$[/tex] and [tex]$Y$[/tex]:
- Option 1:
- [tex]$X$[/tex]: Copper
- [tex]$Y$[/tex]: Glass
- Evaluation:
- Copper is a conductor, not an insulator.
- Glass is generally an insulator, not a semiconductor.
- This option does not fit.

- Option 2:
- [tex]$X$[/tex]: Rubber
- [tex]$Y$[/tex]: Copper
- Evaluation:
- Rubber is an insulator, which fits the criteria for X.
- Copper is a conductor, not a semiconductor.
- This option does not fit because copper is not a semiconductor.

- Option 3:
- [tex]$X$[/tex]: Paper
- [tex]$Y$[/tex]: Silicon
- Evaluation:
- Paper is an insulator, which fits the criteria for X.
- Silicon is a semiconductor, which fits the criteria for Y.
- This option fits both criteria.

- Option 4:
- [tex]$X$[/tex]: Silicon
- [tex]$Y$[/tex]: Glass
- Evaluation:
- Silicon is a semiconductor, not an insulator.
- Glass is generally an insulator, not a semiconductor.
- This option does not fit.

Therefore, the best match to complete the chart is:
- [tex]$X$[/tex]: Paper
- [tex]$Y$[/tex]: Silicon

Thus, the correct answer is:

[tex]$X$[/tex]: Paper \\
[tex]$Y$[/tex]: Silicon
