Which HID Xenon bulbs?

[ours6hers]

Hi

Please can someone tell my what type of bulb i would need in my C5 S6? I thought it would be quite straight forward but there seems to be a few to choose from. I don't have the car with me either as the wifes got it and need to get a new set of bulbs. For example, would D2S ones fit?

Thanks
