Quizplus · Accepted Answer

This sentence has a prepositional error in using an idiomatic expression. The full form of the idiom is "behind someone's back" which means 'without someone's knowledge or approval'. All options except option C use inappropriate prepositions (...beyond/ between/ below/ beneath). Option C uses the right preposition and a right form of the idiom (was discussed behind my back), so it is the correct answer
