For most test takers, Data Insights is the most challenging section on the GMAT, with test takers scoring several points lower on average on DI than on Quant or Verbal and completing the section with less time to spare.

Hi,
the solution says A is the answer, but I think D should be the answer because, you can solve for B, given any number of n, and determine if side of the equality equals the other...(given that x > 0)...
so both solutions should work.. any thoughts??

First of all, welcome to the GMATClub 
After that, I agree with Andr359. It's better to post the question in order to recieve replies
By the way, I have looked at the question 142 in OG 11/Section DS. But, as u speak about an integer n?, I'm not 100% sure that the question that I look is the one that u have a problem with.
The question is asking basically 9^(x) + 9^(-x) = b ?
The first statment is right. U have already powered by 2 the equation and found the equality that we are looking for.
The second is just saying us x > 0. But, we have no relationship between x and b. In other words, 9^(x) + 9^(-x) = 4*a or 9^(x) + 9^(-x) = 2 or so on. We have no clue about 9^(x) + 9^(-x) = b for sure. That is insufficient
