In the question below, a sentence is given, divided

Solution

Part D is the odd part. A opens the sentence by establishing the subject and main predicate — central banks in emerging economies face.  B follows A directly by introducing the object — the acute dilemma of raising interest rates.  C follows B by specifying the purpose of raising rates — to contain imported inflation driven by currency depreciation. E concludes by introducing the competing risk created by the same rate increase — while simultaneously risking a sharp contraction in domestic credit and investment. The logical chain is A → B → C → E, forming — "Central banks in emerging economies face the acute dilemma of raising interest rates to contain imported inflation driven by currency depreciation while simultaneously risking a sharp contraction in domestic credit and investment." D is the odd part. It introduces an entirely unrelated historical geography fact — the Silk Road connected ancient China to Mediterranean trading ports — which belongs to a discussion about ancient trade history. It shares no grammatical link with any surrounding part, and the sentence is fully coherent and complete without it. Hence (B) ABCE is the correct answer.
