Baku is the capital and largest city of Azerbaijan, located on the Caspian Sea. It's an important cultural and economic center in the South Caucasus region.

Budapest is the capital of Hungary, formed by the unification of Buda and Obuda on the west bank and Pest on the east bank of the Danube River. It's a major cultural and economic hub in Central Europe.

Cairo is the capital of Egypt, located on the Nile River. It's the largest city in the Arab world and famous for its proximity to the Giza Pyramids and rich ancient history.

Georgetown is the capital of Guyana, the only English-speaking country in South America. It's located on the Atlantic coast and named after British King George III.

Abuja is the capital of Nigeria, having replaced Lagos in 1991. It's a planned city located in the center of the country. Nigeria is the most populous country in Africa. Suriname, Botswana, and Algeria are all African countries but Abuja is not their capital.

The 2009 United Nations Climate Change Conference (COP15) was held in Copenhagen, Denmark. This summit produced the Copenhagen Accord, a significant international agreement on climate change mitigation. Dubai, New York, and London have not hosted UN climate summits in 2009.

South Africa has three capital cities: Pretoria (executive), Cape Town (legislative), and Bloemfontein (judicial). The question specifically asks for the judicial capital, which is Bloemfontein. Cape Town is the legislative capital, not judicial.

Tel Aviv is Israel's financial and technological center, housing the Tel Aviv Stock Exchange, numerous banks, financial institutions, and many international companies. It is the economic hub of Israel, often called 'The Silicon Valley of the Middle East' due to its concentration of high-tech industries and startups.

Lagos is the odd one out because it is not a national capital. Abuja is the capital of Nigeria, Caracas is the capital of Venezuela, and Sucre is the constitutional capital of Bolivia. Lagos was formerly Nigeria's capital but lost that status to Abuja in 1991.

Port Louis is the capital and largest city of Mauritius, located on the northwest coast of the island. It has been the capital since 1735 when it was founded by the French.

Hyderabad has sister city relationships with Munich (Germany) and Dubai (UAE). These partnerships foster cultural, economic, and technological exchange. Moscow and Bahamas are not sister cities of Hyderabad. Note: The question only states 'Hyderabad' without context - this could be Hyderabad, India, but the answer key assumes this.
