The Nobel Prize in chemistry was awarded to three scientists for their discovery that plastic can be made electrically conductive--an advance that has led to improvements in film, television screens, and windows.

(A) that plastic can be made electrically conductive--an advance that has led
(B) that plastic can be made electrically conductive--this advance leading
(C) that plastic can be made to be electrically conductive, and this advance led
(D) of plastic's ability to be made electrically conductive, with this advance leading
(E) of plastic being able to be made electrically conductive--an advance that has led

How I have reached to A and E:
B=> This advance leading is awkward.
C=> To be is unnecessary.
D=> With this ability leading.

I am in confusion about the being in E. How can I be sure that BEING in E is wrong. I am in doubt. I could eliminate E, but i did not.

Another thing that I have thought:
They have been awarded for the discovery of XYZ.
=> If this sentence is correct, then E is right in using of XX.

Experts, please help/
