When odysseus first wakes up in ithaca, he thinks that the phaecians fooled him, placed him on the wrong island, and stole some of his treasure. he curses them because of this. odysseus believed he was placed on the wrong island because athena made ithaca look different so he wouldn't recognize it.
I think it's A. It is definally not the climax as this happens when Beowulf kills the monster. It's not the resolution either as it is the first part of the text. Also, exposition seems a little unrelated.
