Hmmm
If the listed options are correct, then some of those are illegal imports.
Legal licence free (excluding RFID)
27MHz
49MHz
433MHz
446MHz (only FM walkie talkies and one AMBE digital Codec model)
866 to 870MHZ (868MHZ)
2.4GHz ISM band
5.8GHz ISM band (WiFi and Registered Outdoor PMP only in some countries)
RFID http://www.rfid-handbook.de/rfid/frequencies.html
Satellite is mostly Ku for DTH, but Tooway VSAT uses Ka band
So some of the stuff is illegal if the questions are correct.
Other stuff has used DIFFERENT bands at different times... Legally. Such as Mice and Keyboard have variously used 27MHz, 49MHz, 433MHz, 868MHz and 2.4GHz. MS has used 27MHz and 2.4GHz for similar models.
Note that 2.4GHz is not always Bluetooth or WiFi, even if it's digital.
Some licensed gear uses 1.4GHz
Ireland has 10.450GHz for licence free Movement detectors
3.6GHz and 10.5GHz. FWALA (Licensed Fixed Wireless).
I think the quiz is flawed.
418 & 915MHz is USA
