I presume this artistic illustration shows the third option
I believe so, although we should bear in mind that it is indeed only an artist's impression.
The proposal states that:
"We are not yet in a position to conclude the precise design of such a new runway. Considerations include the exact length of the runway, how it would be operated and how the related infrastructure, such as new taxiways, aprons and passenger terminal and surface access connections would be provided."
And I think I'm right in saying that the artist has drawn the taxiway in the foreground too close to the 26 threshold to be usable as an end-around.
