Patty makes a table of the symbols used for the parts of an electric circuit.

\begin{tabular}{|c|c|}
\hline
Symbol & Component \\
\hline
[tex]$Q$[/tex] & \\
\hline
[tex]$-1 / 1-$[/tex] & \\
\hline
[tex]$-\sigma \circ$[/tex] & \\
\hline
[tex]$\sim$[/tex] & \\
\hline
\end{tabular}

What label should Patty place in the marked cell?

A. Battery
B. Switch
C. Resistor
D. Bulb

Let's start by examining the given table of symbols and the corresponding components in an electric circuit:

[tex]\[ \begin{array}{|c|c|} \hline \text{Symbol} & \text{Component} \\ \hline Q & \\ \hline -1 / 1- & \\ \hline -\sigma \circ & \\ \hline \sim & \\ \hline \end{array} \][/tex]

We need to determine the appropriate label for each symbol based on the standard symbols used in electrical diagrams.

### Matching Symbols to Components

1. Understanding the Symbols:
- \( Q \): This symbol is often used to represent a battery in circuit diagrams.
- \( -1 / 1- \): This pattern resembles a switch symbol, where the '1' and '-1' are indicative of the open and closed states of a switch.
- \( -\sigma \circ \): The combination of a line with a sigma (Ļƒ) and a circle is a traditional representation of a resistor.
- \( \sim \): This is generally used to indicate an alternating component like a bulb or an AC power source but is commonly recognized for bulbs in simple circuits.

2. Identifying the Marked Cell:
- The problem specifically highlights the marked cell with the symbol \( -\sigma \circ \).

### Conclusion
Given the standard meanings of these symbols in an electric circuit:
- \( -\sigma \circ \) is the symbol for a Resistor.

### Final Labeled Table

[tex]\[ \begin{array}{|c|c|} \hline \text{Symbol} & \text{Component} \\ \hline Q & \text{Battery} \\ \hline -1 / 1- & \text{Switch} \\ \hline -\sigma \circ & \text{Resistor} \\ \hline \sim & \text{Bulb} \\ \hline \end{array} \][/tex]

So, the label that Patty should place in the marked cell corresponding to the symbol \( -\sigma \circ \) is:
Resistor.
