UPSC 2004: Consider the following statements: 1. Montenegro and Serbia agreed to a new structure for the Yugoslav Federation. 2. Croatia remained under the Hungarian Administration until the end of First World War. 3. Claims to Macedonian Territory have long been a source of contention between Belgium and Greece. 4. In 1991, Slovenia declared independence from Czechoslovakia. Which of the statements given above are correct?

1️⃣ In 2002-03 Serbia and Montenegro signed the Belgrade Agreement/Constitutional Charter creating a new State Union, so statement 1 is right. ([en.wikipedia.org](https://en.wikipedia.org/wiki/Constitutional_Charter_of_Serbia_and_Montenegro?utm_source=openai)) 2️⃣ Croatia was constitutionally linked to the Hungarian crown by the 1868 Nagodba and remained under Hungarian jurisdiction until the Austro-Hungarian collapse in 1918, so statement 2 is correct. ([britannica.com](https://www.britannica.com/event/Nagodba?utm_source=openai)) 3️⃣ The long-running dispute over the name and territory of Macedonia has been between Greece and (North) Macedonia/Bulgaria, not Belgium, so statement 3 is wrong. ([en.wikipedia.org](https://en.wikipedia.org/wiki/Macedonia_naming_dispute?utm_source=openai)) 4️⃣ Slovenia declared independence from Yugoslavia on 25 June 1991, not from Czechoslovakia, so statement 4 is wrong. ([en.wikipedia.org](https://en.wikipedia.org/wiki/Statehood_Day_%28Slovenia%29?utm_source=openai)) Therefore only statements 1 and 2 are correct ⇒ option (a).
