Match List-I with List-II and select the correct answer by using the codes given below the lists: List-I A) Donetz B) Kuzantsk C) Lancashaire D) Saar List-II 1) Germany 2) U.K. 3) Russia 4) Ukraine

Donetz (Donbas) is the coalfield in eastern Ukraine, so A matches 4. Kuznetsk (Kuzbass) is in Siberia, Russia, so B matches 3. Lancashire is the old English coalfield and textile region of the U.K., so C matches 2. The Saar coalfield lies in Saarland, Germany, near the French border, so D matches 1.

Option B is correct: A-4, B-3, C-2, D-1.

Why the others fail: Option A puts Donetz with Germany and Saar with Ukraine. Option C puts Donetz with Russia and Kuznetsk with Ukraine, which reverses the two eastern basins. Option D puts Donetz with Germany and Saar with Ukraine, so it has two errors.

Core concept: the major coal basins of Europe and Asia and their link to steel and heavy industry. Mains angle: the Ruhr, Saar, Donbas and Kuzbass as examples of coal-steel regions, useful for questions on industrial location and the decline of old industrial belts.

Trap: candidates swap Donetz and Kuznetsk because both sound Slavic. Fix each basin to its country on a map.
