The correct answer for the given mathematical question above would be option A. The statement that shows two polynomials 4x + 6 and 2x^2-8x demonstrating the closure property when multiplied is that, 8x^3-20x^2-48x is a polynomial. The answer is option A for the given reason: (4x+6) (2x^2 - 8x) = 8x^3 - 20x^2 - 48x
