The property of being dim in the visible part of the spectrum was not unusual for quasars. In fact, quasars are known to be extremely bright in the radio and other non-visible parts of the spectrum, which is why property B was listed as unusual. Properties C and D were also unusual, as they indicated that the light from quasars was being emitted by hot, energized gas rather than by the cooler gas found in ordinary stars.
