Statement 1:
Tells us top 4 contributed 56% so rest 2 among top contributors must have contributed 11.8%. This does not specify how much x contributed so A and D are out.

Statement 2:
Tells us Country X paid 4.8 % of the total expenditures. This just tells us X contribution but nothing about other's so B is out.

Combining together is also not going to yield any information because 11.8/2 = 5.9 that can contributed by each remaining top contributor, in this case X will not be among top contributors. However if 5th top contributor added 7 percent then X become the 6 top contributor.

Answer E.

Statement 1 tells us the sum of expenditures for 4 out of 6 countries. so 67.8% - 56% for 2 of the countries. Statement 1 says that X, if part of the 6, is #5 or #6. We don't know enough to determine what X paid.

Statement 2 says that 4.8% of the expenses were paid by X. But this statement doesn't tell us how 4.8% relates to the whole or any other country's contributions. Insufficient.

To determine if we have enough information together, take 67.8% - 56% to see how much #5 & #6 paid. We get 11.8%. 4.8% is not even half of that, so it is possible that 2 other countries contributed more than 4.8% in order to make up the last of the % of the top 6.

If X had contributed greater than half the 11.8% remaining, then we would know that they were # 5 because there would be no way for 2 other countries to contribute more than X and leave X out. But, since X only contributed 4.8%, then it is possible that some other country paid 4.9% and another country paid 6.9%, thus making the 11.8% + 56% = 67.8% of the top 6, leaving X on the outside of the top 6.

Yes, the answer should indeed be E.
I have no new explanation to offer. It's pretty clear from the explanation given above. :)

I think E is a pretty straight forward pick here
