I thought that B was correct too, but with some research i figured out that in NX-OS there is a possibility to configure a reference-bandwith in isis for the metric calculation.
But it seems that for IOS XE , and IOS XR B would be correct
So it is not correct for all cisco devices
I think it is B instead of F
