**Topic: Possible Echelon Forms of the Standard Matrix for a Linear Transformation**

**Description:**  
Describe the possible echelon forms of the standard matrix for a linear transformation \( T \) where \( T: \mathbb{R}^4 \to \mathbb{R}^3 \) is onto.

---

**Echelon Form Examples:**

The leading entries, denoted by ■, may have any nonzero value; the starred entries, denoted by *, may have any value (including zero). Select all that apply.

**Matrices:**

- **A.** 
  \[
  \begin{bmatrix}
  \blacksquare & * & * & * \\
  0 & \blacksquare & * & * \\
  0 & 0 & \blacksquare & * \\
  \end{bmatrix}
  \]

- **B.** 
  \[
  \begin{bmatrix}
  \blacksquare & * & * & * \\
  0 & 0 & \blacksquare & * \\
  0 & 0 & 0 & \blacksquare \\
  \end{bmatrix}
  \]

- **C.** 
  \[
  \begin{bmatrix}
  0 & 0 & 0 & \blacksquare \\
  0 & 0 & 0 & 0 \\
  0 & 0 & 0 & 0 \\
  \end{bmatrix}
  \]

- **D.** 
  \[
  \begin{bmatrix}
  \blacksquare & * & * & * \\
  0 & \blacksquare & 0 & * \\
  0 & 0 & \blacksquare & * \\
  \end{bmatrix}
  \]

- **E.** 
  \[
  \begin{bmatrix}
  0 & \blacksquare & 0 & * \\
  0 & 0 & \blacksquare & * \\
  0 & 0 & 0 & \blacksquare \\
  \end{bmatrix}
  \]

- **F.** 
  \[
  \begin{bmatrix}
  \blacksquare & * & * & * \\
  0 & 0
