### Question
What matrix would translate by [1, 2, 3] be?

### Options
1. 
   ```
   [ 1  0  0  0 ]
   [ 0  2  0  0 ]
   [ 0  0  3  0 ]
   [ 0  0  0  1 ]
   ```

2. 
   ```
   [ 1  0  0  0 ]
   [ 0  1  0  0 ]
   [ 0  0  1  0 ]
   [ 1  2  3  1 ]
   ```

3. 
   ```
   [ 1  0  0  0 ]
   [ 0  1  0  0 ]
   [ 0  0  1  0 ]
   [ 1  2  3  0 ]
   ```

4. 
   ```
   [ 1  0  0  0 ]
   [ 0  1  0  0 ]
   [ 0  2  0  0 ]
   [ 0  0  3  0 ]
   ```

### Explanation
The goal is to determine which matrix corresponds to a translation transformation by the vector [1, 2, 3] in a 3D space. The translation matrix takes the form:

```
[ 1  0  0  Tx ]
[ 0  1  0  Ty ]
[ 0  0  1  Tz ]
[ 0  0  0  1  ]
```

Where Tx, Ty, Tz are the translation components in the x, y, and z directions, respectively. Therefore, the correct matrix that translates by [1, 2, 3] is:

```
[ 1  0  0  1 ]
[ 0  1  0  2 ]
[ 0  0  1  3 ]
[ 0  0  0  1 ]
``` 

Thus, the correct option is the second one with an adjusted fourth row to `[ 0  0  0  1 ]
