Answers A, E are correct: Network range for 2a01:c30:16:7009::3800/118 2a01:0c30:0016:7009:0000:0000:0000:3800- 2a01:0c30:0016:7009:0000:0000:0000:3bff Network Range for 2a01:0c30:0016:7009::3a00/120 2a01:0c30:0016:7009:0000:0000:0000:3a00- 2a01:0c30:0016:7009:0000:0000:0000:3aff Network range for 2a01:0c30:0016:7009::3b00/120 2a01:0c30:0016:7009:0000:0000:0000:3b00- 2a01:0c30:0016:7009:0000:0000:0000:3bff (As you see it ends with 2a01:0c30:0016:7009:0000:0000:0000:3bff So that means 2a01:0c30:0016:7009:0000:0000:0000:3c00/120 is out of the picture)

And why not ::3c00/120 ? Is the same, isn´t it?
