You are correct!
I agree with Ashley that your answer is correct.
In order to get r^2 - 49, you have have the equation in A. Then, you would multiply the like terms together to get the final answer of r^2 - 49.
(r - 7)(r +7) = r^2 - 49
r x r = r^2
-7 x 7 = -49
r^2 - 49 = r^2 - 49
So yes, A is the correct answer.
