Having read the excerpt, the answer to the question is letter b. Millay finds beauty in the autumn world but resents the rebirth of spring because she sees death and sorrow everywhere. The other choices given were not that relevant compared to what is chosen.
I believe that Eurycleia doesn't want Telemachus to leave because she doesn't want to leave the palace unprotected.
She believes that if he leaves, the suitors will try to plunder the palace and steal everything, and there will be no one to protect either the palace, or Penelope.
The narrative point of view is third person point of view.
