• It seems that the option 'd' would be the correct answer here. This is because if two men were dancing with the same woman, or two women were dancing with the same man, there would be an odd number of people left. Presuming these people must be dancing in pairs, there would be one person left over, and hence everyone would not be dancing together. However, it has to be said that the wording of the question is unclear, so there may well be another answer.
