The correct answer is B. It shows that he prefers the familiar and ordinary.
Explanation
The fragment presents a scene in which a toad, a rat, and a Mole discuss the possibility of undertaking a new adventure. However, the rat did not want to go with the toad and the mole since his attitude was "The Rat only snorted and thrust his hands deep into his pockets, remaining where he was". Later, he apologizes to the toad because he did not want to be included in that plan, as expressed by saying “I beg your pardon,” said the Rat slowly, as he chewed a straw, “but did I overhear you say something about ‘WE,’ and ‘START,’ and ‘THIS AFTERNOON?’”
Additionally, he shows his preference by saying “I'm not coming, and that's flat. And I AM going to stick to my old river, AND live in a hole, AND boat, as I've always done. "According to the above, it can be established that the rat did not want to embark on an adventure with the mole and the toad because he preferred to continue his life ordinarily as he had always done in the places that were familiar to him.
