11x^2-x+15

A is the correct option.

Step-by-step explanation:

We have to find the sum of the polynomials (x^2-x+8)+(10x^2+7)

On removing the parentheses, we get

x^2-x+8+10x^2+7

Group the like terms

x^2+10x^2-x+8+7

Combine the like terms

11x^2-x+15

Therefore, the sum of the polynomials is 11x^2-x+15

A is the correct option.
