The proper sequence of emissions corresponding to the sequence SSB-Voice without carrier, USB-Voice with carrier, FM-Voice and SITOR TELEX is:

Correct Answer: Option C — J3E, H3E, F3E, F1B.

Emission designators follow international standards: J3E is single-sideband suppressed carrier, H3E is single-sideband with full carrier, F3E is frequency modulation for voice, and F1B is frequency-shift keying used for SITOR (NBDP) telex. These designations are critical for proper radio equipment configuration and compliance with GMDSS operational requirements.
