b. -2x^3 + 6x^2 + 6x + 9
c. -2x^5 + 10x^2 + 6x + 9
d. -2x^3 + 6x + 9

 the correct option is (B)

Step-by-step explanation:  We are given to select the correct polynomial that represents the following sum :

To find the above sum, we need to add the coefficients of the similar powers of x.

The summation is as follows :

Thus, the required sum is
