At the start of the passage, Panna's own child was in her lap and she 'was singing softly to put him to sleep' — the 'him' here refers to her own child, not the Prince, who was already asleep. So the correct answer is 'Put her own child to sleep', option (2).
PRO TIP
Re-check your working by substituting the answer back into the original question.
