I believe the best definition of the word 'termagant' based on Irving's descriptions of Mrs. Walker would be "ill-tempered".
You can look for a part of the word that is added to that word, to the root of the word. For example, 'happy' is the base of the word, or the root. When you say 'happily', you see that -ly has been added to the core word, and that is the suffix.
The answer is A. Now I can relax
In Book 1, Odysseus is with Calypso on Ogygia.
The story takes place ten years after the Trojan War, and Odysseus is the only hero who hasn't yet returned home to his wife Penelope in Ithaca. He is basically trapped on the island of Ogygia, with the goddess Calypso, who fell in love with him and won't let him leave.
I would go with A. B would come next. So yeah A
