Which unit of measurement, as formally defined, is an absolute unit that is used to quantify received
signal power levels on a logarithmic scale?

Yeah, it's definitely C. dBm is the absolute unit for received signal strength on a log scale. dBi trips people up since it's relative (antenna gain), not absolute. Seen this exact kind of wording come up in a lot of CWNA practice sets.
Probably C. dBm is the only absolute unit here, while dBi is often a trap since it's relative antenna gain.
It’s C, dBm is the absolute measurement referenced to 1 milliwatt and used for received signal power. SNI and VSWR aren’t power units, dBi is for antenna gain. Pretty sure this lines up with CWNA fundamentals.
