From the words or group of words lettered A to D, choose the word or group of words that best completes each of the following sentences.
John and James are good friends; they are very fond of............

Answer Details

The correct answer is "each other". The sentence indicates that John and James have a close friendship, and the phrase "fond of" implies that they have positive feelings towards each other. "Themselves" refers to the individuals separately, while "one and another" is not a grammatically correct phrase. "Them" is not specific enough and could refer to other people or objects.
