The pattern is letter-number: L1, J2, _, F4, D5. Letters decrement by 2 (L, J, H, F, D), numbers increment by 1.
After "#", the digit repeats, and the next letter increases. The increase is +4 more than the previous step from the first letter:
L → O (+3), J → Q (+7), so next must be H → S (+11), then F → U (+15), D → W (+19).
The final part "~" repeats the second digit, incremented by 1.
Therefore, the missing code is H3#3S4~4, which is not an option.
⇒ None of these.
