Match each polynomial with the appropriate explanation regarding the roots of the related polynomial equation.

A (x+5)(x−4)[x−(8−i)][x−(8+i)]
B (x+7)(x−9)(x−2)
C (x+2i)(x−2i)(x+2)^2
D (x+3)(x−1)(x+2)^2

(1) The related polynomial equation has a total of three roots; all three roots are real.
(2) The related polynomial equation has a total of four real roots; all four roots are real and one root has a multiplicity of 2 .
(3) The related polynomial equation has a total of four roots; two roots are complex and two roots are real.
(4) The related polynomial equation has a total of three roots; all three roots are real and one root has a multiplicity of 2 .
(5) The related polynomial equation has a total of two roots; both roots are real and have a multiplicity of 2 .
(6) The related polynomial equation has a total of four roots; two roots are complex and one root is real with a multiplicity of 2 .
