Given the matrices A = [[1, 2], [3, 4]] and B = [[5, 6], [7, 8]], what is the resulting matrix C from the operation C = [A B]?

Dimensionality of Concatenated Matrices

A matrix $\mathbf{W}$ is formed by horizontally combining two other matrices, $\mathbf{A}$ and $\mathbf{B}$, such that $\mathbf{W} = [\mathbf{A} \mathbf{B}]$. If $\mathbf{W}$ is given as [[1, 0, 5, 6], [2, 1, 7, 8]], which of the following options correctly identifies a possible pair for matrices $\mathbf{A}$ and $\mathbf{B}$?
