This is tricky to eliminate. You can try going through the ordering rules…but all of the answer choices obey those rules.
Getting this right depends on the deduction that Y can’t go first if Z is sixth. Only G can sing Y and Z. The same singer can’t sing the first and the last song.
If Y went first and Z went sixth then G would sing both the first and last songs.
B is CORRECT because Y can’t be in first if Z is in sixth.
