The chart shows the voltage of four electric currents.

Voltage of Currents
\begin{tabular}{|l|l|}
\hline Current & \multicolumn{1}{|c|}{Volts (V)} \\
\hline W & 9.0 \\
\hline [tex]$X$[/tex] & 1.5 \\
\hline [tex]$Y$[/tex] & 3.0 \\
\hline [tex]$Z$[/tex] & 4.5 \\
\hline
\end{tabular}

Which is best supported by the data in the chart?

A. Current W flows at a higher rate than Current [tex]$Z$[/tex].
B. Current [tex]$Y$[/tex] flows at a lower rate than Current [tex]$X$[/tex].
C. Current [tex]$X$[/tex] has a lower potential difference than Current [tex]$Y$[/tex].
D. Current [tex]$Z$[/tex] has a greater potential difference than Current W.

Let's go through the given statements one by one and compare the voltages provided in the chart to determine which is best supported by the data.

Here are the voltages for reference:
- Voltage of Current W: 9.0 V
- Voltage of Current X: 1.5 V
- Voltage of Current Y: 3.0 V
- Voltage of Current Z: 4.5 V

1. Current W flows at a higher rate than Current Z.
- Comparing the voltages of W and Z:
- Voltage of W: 9.0 V
- Voltage of Z: 4.5 V
- Since 9.0 V is greater than 4.5 V, this statement is True.

2. Current Y flows at a lower rate than Current X.
- Comparing the voltages of Y and X:
- Voltage of Y: 3.0 V
- Voltage of X: 1.5 V
- Since 3.0 V is not lower than 1.5 V, this statement is False.

3. Current X has a lower potential difference than Current Y.
- Comparing the voltages of X and Y:
- Voltage of X: 1.5 V
- Voltage of Y: 3.0 V
- Since 1.5 V is less than 3.0 V, this statement is True.

4. Current Z has a greater potential difference than Current W.
- Comparing the voltages of Z and W:
- Voltage of Z: 4.5 V
- Voltage of W: 9.0 V
- Since 4.5 V is not greater than 9.0 V, this statement is False.

So, the statements compare as follows:

- Current W flows at a higher rate than Current Z: True
- Current Y flows at a lower rate than Current X: False
- Current X has a lower potential difference than Current Y: True
- Current Z has a greater potential difference than Current W: False

Therefore, the statements that are best supported by the data in the chart are:
- Current W flows at a higher rate than Current Z.
- Current X has a lower potential difference than Current Y.
