The 1000 individuals...that's the number given by the IUCN Red List Assessment team which included Ted Papenfuss (UC Berkeley), Sergius Kuzmin (Russian Academy of Sciences), and Nasrullah Rastegar-Pouyani from Razi University in Iran. Rastegar-Pouyani has published papers on Neurergus in the Zagros Mountains and Population Assessment Reports, etc. So basically, if anyone knows the real situation, he does. The habitat where they occur is near military installations but it is still threatened by drought and the use of chemicals by locals.
I would guess "B" from your multiple choice, although I wouldn't guess extirpated just yet. Give it 2 or 3 more years.
