- Class A: Art 8, Band 5, Chess 3
- Class B: Art 4, Band 6, Chess 7

If rows represent classes (A then B) and columns represent clubs (Art, Band, Chess), which matrix correctly displays this information?

$\begin{bmatrix}8 & 5 & 3\\4 & 6 & 7\end{bmatrix}$
$\begin{bmatrix}8 & 4 & 0\\5 & 6 & 7\end{bmatrix}$
$\begin{bmatrix}8 & 4\\5 & 6\\3 & 7\end{bmatrix}$
$\begin{bmatrix}8 & 5 & 3\\7 & 6 & 4\end{bmatrix}$
