D. 4

Answer

To find the element in the second row and first column of the given matrix, we can follow these steps:

1. **Identify the Matrix**: The matrix given is `[(6, 1, -4), (-3, 8, 9)]`. This matrix can be represented as:
```
Row 1: 6 1 -4
Row 2: -3 8 9
```

2. **Locate the Row and Column**: We need to find the element located in the second row and the first column.

3. **Identify the Second Row**: The second row of the matrix is `(-3, 8, 9)`.

4. **Identify the First Column**: The first column of the matrix consists of the first elements of each row:
- From Row 1: 6
- From Row 2: -3

5. **Find the Element**: The element in the second row and first column is the first element of the second row, which is `-3`.

Thus, the element in the second row, first column is **-3**.
