Problem Analysis:
We are given a quadratic equation ax^2 + bx + c = 0, and we need to find the difference in the cubes of the roots of the equation.

Let the roots of the equation be α and β.

We need to find (α^3 - β^3).

Statement Analysis:
Statement A: Sum of the roots of the quadratic equation is known.
Statement B: Product of the roots of the quadratic equation is known.

Case Analysis:
Let's analyze the possible cases based on the statements:
1. If we know the sum of the roots (Statement A) but not the product of the roots (Statement B), we cannot determine the difference in the cubes of the roots. This is because the difference in the cubes of the roots depends on both the sum and the product of the roots.
2. If we know the product of the roots (Statement B) but not the sum of the roots (Statement A), we cannot determine the difference in the cubes of the roots. Similar to the previous case, the difference in the cubes of the roots depends on both the sum and the product of the roots.
3. If we know both the sum of the roots (Statement A) and the product of the roots (Statement B), we can determine the difference in the cubes of the roots. This is because we can express the difference in the cubes of the roots in terms of the sum and the product of the roots.

Solution:
Since we can determine the difference in the cubes of the roots using both Statement A and Statement B, the answer is (3).
