### Problem Statement

**Objective:** Find all vectors \( x \) in \( \mathbb{R}^4 \) that are mapped into the zero vector by the transformation \( x \mapsto Ax \) for the given matrix \( A \).

**Matrix \( A \):**

\[
A = \begin{bmatrix}
1 & 2 & 7 & -1 \\
0 & 1 & 3 & -4 \\
0 & 1 & 2 & 3 \\
-3 & 3 & -3 & 10
\end{bmatrix}
\]

### Task

Select the correct choice below and fill in the answer box within your choice:

- **(A).** There is only one vector, which is \( x = [ \; \_ \; ] \).

- **(B).** 
  \[
  \begin{bmatrix}
  \_ \\
  x_3 \\
  \_ \\
  \_
  \end{bmatrix}
  \]

- **(C).** 
  \[
  \begin{bmatrix}
  x_1 \\
  \_ \\
  x_3 \\
  x_4
  \end{bmatrix} \quad \text{with options: }
  \begin{bmatrix}
  \_ \\
  \_ \\
