Well, it's a strange question because the original sentence has so many errors that it's hard to select just one. Let's just go with the point that it says: both...as well as..., which is unidiomatic. With this guide in mind, we can eliminate answer choice (A) and (C).

Answer choice (B) and (E) contain misplaced modifiers. Additionally, (E) contains an unidiomatic found X as Y rather than found X to be Y.

Answer choice (D) is the best answer.

The correct idiom is BOTH X AND Y
ELIMINATE

B. Currently used by only two or three planes a day (hmmm, WHAT is used by only two or three planes a day?), a joint Canadian–Russian study (a joint study was used by two or three planes a day?? THIS MAKES NO SENSE) has found that if air traffic routes over the North Pole are opened to thousands more commercial planes a year, it would be both feasible and desirable.
ELIMINATE

C. A joint Canadian–Russian study, finding it to be both feasible as well as desirable to open air traffic routes over the North Pole, which are currently used by only two or three planes a day, to thousands more commercial planes a year.

. . . has been found AS is unidiomatic (should be FOUND TO BE)
ELIMINATE

Answer: D

ASIDE: In many cases, an incorrect answer choice has several issues. I have just pointed out one issue.
