From the words lettered A to D choose the word or group of words that best completes the sentence.
I don't know what to do with these children. They are always fighting ..

Answer Details

The best word to complete the sentence is "one another." This is because "one another" is a reciprocal pronoun that refers to a mutual action or relationship between two or more people or things. In this context, the sentence suggests that the children are engaged in a continuous cycle of fighting with each other, which implies a reciprocal action. Therefore, the most appropriate option is "one another."
