Concept:Ferdinand, while imprisoned, says that merely seeing the girl he loves each day would make all his suffering bearable.
Explanation:The speaker is Ferdinand, who has been captured on Prospero's island.
He lists his father's death, his own weakness, the loss of his friends, and his captor's threats.
He claims all these burdens become light if he may look upon "this maid" once a day from his prison.
The maid is the young woman Ferdinand has fallen in love with at first sight.
She is Prospero's daughter, whose name is Miranda.
Therefore, "this maid" is clearly Miranda, not Caribel, Sycorax, or Dido.
Answer:B. Miranda
