16-bit PSD & Photoshop CC

[Jikkk]

Hey,
I'm just wondering why I'm getting this message (image bellow) when opening a 16-bit PSD image in Photoshop CC. What option should I choose?
Thanks!

KeyShot renders in sRGB, so the option you have selected should not change the image's appearance.

That said, option number one should not affect or change the image and would be the safest option I think.
