IMO A,C and E are close contenders.

A) While for years several scientists attempted prove that so-called Planet X was a...after removing "but could not" >>> Doesn't look gud

C) While for years several scientists attempted to prove prove that so-called Planet X was a...after removing "but could not" >>> Doesn't look gud

E) While for years several scientists attempted to prove that so-called Planet X was a...after removing "but could not" >>> Looks OK.
