Which one of the following pairs is not correctly matched?

Option 1 is not correctly matched because Slovenia’s capital is Ljubljana, not Bratislava. Authoritative practice materials and country-capital lists identify Ljubljana as the capital of Slovenia and explicitly mark the pairing “Slovenia – Bratislava” as incorrect. Bratislava is the capital of neighbouring Slovakia, whereas Ljubljana is Slovenia’s political and cultural centre. The other three pairs are correctly matched: Seychelles – Victoria, Sierra Leone – Freetown, and Uzbekistan – Tashkent, as shown in standard capital listings. Therefore the mismatched pair among the options is Slovenia: Bratislava (option 1).
