Which thermistor for heat bed?

[MarcoZ76]

Hi
i own a Geeetech Delta G2s, i changed the firmware and now i use Repetier firmware.
I have a difficulty to choose which thermistors for my heat bed.
i have this choice:

- 100k Epcos B57560G010F000
- 100K NTC 3950
- Generic thermistor table

which one of these are stock on my 3d printer delta G2s?

Thanks

Maybe you can check the configuration.h file in the original firmware of G2s:
