The correct answer is 'Sentences A and B' are expressing the meaning of the word. Abode: means 'a place of residence; a house or home.' In Sentence A: 'Abode' is correctly used in this sentence because the state of mind is the house for emotions. In Sentence B: 'Abode' is correctly used in this sentence because someone lived in London and he took up home or house there. So in this context it is right. In Sentence C: 'Abode' is not used correctly. Hence, it cannot be our answer. Instead using 'abode' use 'Lunatic'. So the correct answer is option 2.
