Identify the error in the following sentence: (a) There are people who are likely (b) to fraternise with their (c) own community yet none other. (d) No error.

The error is in part (c). The conjunction 'yet' is incorrectly used; it implies contrast, but here we need a conjunction indicating addition/exclusion. The correct phrase should be 'own community and none other'. 'Yet' introduces a contradictory clause, while the intended meaning is exclusive identification, requiring 'and'. Parts (a) and (b) are correct.
