Parker wound a wire around a large iron nail. He then created an electromagnet by connecting the ends of the wire to different batteries. The table shows the current he measured for each electromagnet.

\begin{tabular}{|c|c|}
\hline Electromagnet & Current (amperes) \\
\hline W & 2 \\
\hline X & 5 \\
\hline Y & 8 \\
\hline [tex]$Z$[/tex] & 3 \\
\hline
\end{tabular}

Which conclusion is best supported by the data?

A. Electromagnet [tex]$W$[/tex] is the strongest.
B. Electromagnet [tex]$X$[/tex] is weaker than electromagnet [tex]$Z$[/tex].
C. Electromagnet [tex]$Y$[/tex] is the strongest.
D. Electromagnet [tex]$Y$[/tex] is weaker than electromagnet [tex]$X$[/tex].

Let's analyze the given data to determine which conclusion is best supported by the measurements of the currents for each electromagnet.

The current measurements given are:
- Electromagnet W: 2 amperes
- Electromagnet X: 5 amperes
- Electromagnet Y: 8 amperes
- Electromagnet Z: 3 amperes

We need to compare these values to draw accurate conclusions.

1. Electromagnet W is the strongest.
- Current for W is 2 amperes.
- This is less than the currents for X (5 amperes), Y (8 amperes), and Z (3 amperes).
- Therefore, this statement is false.

2. Electromagnet X is weaker than electromagnet Z.
- Current for X is 5 amperes.
- Current for Z is 3 amperes.
- Since 5 is greater than 3, this statement is false.

3. Electromagnet Y is the strongest.
- Current for Y is 8 amperes.
- This is greater than the currents for W (2 amperes), X (5 amperes), and Z (3 amperes).
- Therefore, this statement is true.

4. Electromagnet Y is weaker than electromagnet X.
- Current for Y is 8 amperes.
- Current for X is 5 amperes.
- Since 8 is greater than 5, this statement is false.

After analyzing the data, we can conclude that the statement Electromagnet Y is the strongest is best supported by the data.

Hence, the correct conclusion is:
Electromagnet Y is the strongest.
