**Problem: Find the transpose of the matrix.**

Given Matrix:
\[
\begin{bmatrix}
8 & 4 \\
-4 & 0 \\
-7 & 7 \\
\end{bmatrix}
\]

**Options:**

1. \[
   \begin{bmatrix}
   4 & 8 \\
   0 & -4 \\
   7 & -7 \\
   \end{bmatrix}
   \]

2. \[
   \begin{bmatrix}
   4 & 0 & 7 \\
   8 & -4 & -7 \\
   \end{bmatrix}
   \]

3. \[
   \begin{bmatrix}
   8 & -4 & -7 \\
   4 & 0 & 7 \\
   \end{bmatrix}
   \]

4. \[
   \begin{bmatrix}
   -7 & 7 \\
   -4 & 0 \\
   8 & 4 \\
   \end{bmatrix}
   \]

**Explanation:**

The transpose of a matrix is formed by swapping the rows and columns. For the given matrix:

- Row 1: \([8, 4]\) becomes Column 1: \([8, -4, -7]\)
- Row 2: \([-4, 0]\) becomes Column 2: \([4, 0, 7]\)

Therefore, the correct transpose is Option 3:
\[
\begin{bmatrix}
8 & -4 & -7 \\
4 & 0 & 7 \\
\end{bmatrix}
\]
