Answer:
B. Hate
Step-by-step explanation:
When we use the word Hate, we are expressing how strongly, intensely we dislike something or someone. In this case, the speaker clearly is trying to show how unwilling she or he is to watch their little sister because they can not put up with it. He or she does not like at all doing it, and by saying hate with expression she or he can show their mood and meaning of how they feel about it.
