219 MHz to 220 MHz and 420.0 MHz to 420.1 MHz
C
902.0 MHz to 902.1 MHz
D
All these choices are correct
Answer Notes
To foster weak-signal propagation experiments and traditional Morse code operations, the FCC sets aside specific portions of certain VHF bands. Specifically, the bottom 100 kHz of both the 6-meter band (50.0 to 50.1 MHz) and the 2-meter band (144.0 to 144.1 MHz) are strictly reserved for CW (Continuous Wave) emissions only.
Operating voice, digital, or any other mode in these bottom segments is a violation of FCC rules. The other distractors list UHF frequencies or arbitrary segments that do not share this specific regulatory CW-only protection.
