At which one of the cities labelled as A, B, C and D on the given map of Europe was the historic treaty between NATO and Warsaw Pact countries signed in 1998 ?

The treaty known as the Warsaw Pact (formally the Warsaw Treaty of Friendship, Cooperation and Mutual Assistance) was signed in the Polish capital, Warsaw. School texts explicitly state the pact was named after the city where the treaty was signed — Warsaw — and list the Soviet Union and seven East European states as original signatories, making Warsaw the signing location [1]. Official historical summaries likewise record that the Warsaw Treaty Organization was established by a treaty signed in Warsaw on 14 May 1955, confirming Warsaw as the place of signature [2]. On the map provided, the city labelled C corresponds to Warsaw, so option 3 (C) is correct.
