Wait, is this a trick question? I'm going to go with D) Counter, but I'm secretly hoping it's a Unicorn Metric that none of us have heard of.

Ooh, this is a tough one. I'm going to guess C) Summary, just because it sounds like it could handle a range of values.

Hmm, this one's tricky. I'm thinking Gauge, since it can go up and down, but I'm not 100% sure.
