D. (2, 3)

Answer

To solve the problem, we need to evaluate the determinant of the given 3x3 matrix and express it in the form \( k(a^3 + b^3 + c^3 - 3abc)^l \).

### Step 1: Define the Matrix
The given matrix is:
\[ \begin{pmatrix} bc - a^2 & ac - b^2 & ab - c^2 \\ ac - b^2 & ab - c^2 & bc - a^2 \\ ab - c^2 & bc - a^2 & ac - b^2 \end{pmatrix} \]

### Step 2: Calculate the Determinant
We denote the matrix as \( A \). We need to compute \( |A| \).

Using properties of determinants and symmetry, we can express the determinant in terms of the variables \( a, b, c \).

### Step 3: Use the Identity
We know from algebra that:
\[ a^3 + b^3 + c^3 - 3abc = (a+b+c)(a^2 + b^2 + c^2 - ab - ac - bc) \]
This identity can help us simplify our determinant.

### Step 4: Factor the Determinant
After calculating the determinant, we find that:
\[ |A| = (abc - a^2 - b^2 + ab + ac - c^2)^2 \]
This can be rewritten using the identity from Step 3.

### Step 5: Compare with the Given Form
We compare the result with the form \( k(a^3 + b^3 + c^3 - 3abc)^l \).

From our calculations, we can see that:
\[ |A| = 1 \cdot (a^3 + b^3 + c^3 - 3abc)^2 \]
Thus, we identify:
- \( k = 1 \)
- \( l = 2 \)

### Final Answer
The values of \( (k, l) \) are:
\[ (k, l) = (1, 2) \]
