902.0 MHz to 902.1 MHz
D
All these choices are correct
Answer Notes
The FCC Part 97 rules set aside specific, narrow segments at the very bottom of the 6-meter (50 MHz) and 2-meter (144 MHz) bands exclusively for CW (Continuous Wave or Morse code) operation. Specifically, 50.0 to 50.1 MHz and 144.0 to 144.1 MHz are reserved for this purpose.
This allocation provides a quiet zone for weak-signal CW operations, protecting them from the interference of wider-bandwidth modes like voice or digital. Distractors mention other bands which do not have these specific CW-only bottom edges mandated by the FCC in the same way.
