The matrix shown in the image is:

\[
\begin{bmatrix}
1 & 2 \\
3 & 4 \\
5 & 6
\end{bmatrix}
\]

The subscript \( a_{ij} \) refers to the element located in the \(i\)-th row and \(j\)-th column of the matrix. For \( a_{12} \), this means the element in the first row and second column.

Looking at the first row and second column, we find the value is **2**.

Thus, the correct answer is:

**c. 2**
