Gauge, of course! Unless the question is trying to 'gauge' our knowledge, in which case I'm completely lost.

I'm going to go with the classic: 'D) Counter, because I counter-propose that all the other options are wrong.'

Gauge, without a doubt. Counter is for monotonic increases, and Histogram is for value distributions, not single values.

Counter seems more like a cumulative value, while Gauge is more suitable for a single number that can go up and down.

I'm not sure, but I think D) Counter could also be a possibility.
