NATO's headquarters were initially established in London in 1949 at 13 Belgrave Square. In April 1952, the headquarters moved to Paris, initially housed at the Palais de Chaillot, then to a purpose-built building at Porte Dauphine in 1960. Following France's decision in 1966 to withdraw from NATO's integrated military command, the headquarters were relocated to Brussels, Belgium, with the new site inaugurated on 16 October 1967. Later, due to inadequacies of the old facilities, a new modern headquarters building was constructed across Boulevard Leopold III in Brussels, completed in 2017 and occupied in 2018. Therefore, the headquarters shifted from London to Brussels in 1967, not 1956 as the option states, but among the given options, Brussels is the correct city associated with the headquarters shift.

NATO's initial civilian headquarters was established in London in 1949 at 13 Belgrave Square. It then moved to Paris in April 1952, initially housed at the Palais de Chaillot and later to a purpose-built building at Porte Dauphine in 1960. In 1967, following France's withdrawal from NATO's integrated military command, the headquarters relocated to Brussels. The temporary building constructed in 1966 served as NATO's headquarters for 51 years until a new, modern headquarters was opened across the road in 2018. The old building was returned to Belgium in 2020. Although option A incorrectly lists Warsaw in 1950 and the last date as 2015, it is the closest option regarding the sequence of locations and moves. The correct dates for the last move are 2017-2018, but no option matches exactly, so A remains the best choice.
