The correct answer is Manila, the capital of the Philippines, located on the island of Luzon, as confirmed by the CIA World Factbook's country profile. Manila has served as the seat of the Philippine government for most of the country's modern history, first under Spanish colonial rule, then under American administration, and continuing after independence in 1946. However, from 1948 to 1976, Quezon City, a planned city adjacent to Manila, was officially designated the national capital as part of a mid-twentieth-century urban planning vision, before a 1976 presidential decree restored Manila's capital status, which it retains today as the seat of key national institutions including Malacanang Palace. Quezon City (option A) is therefore a plausible-looking distractor rooted in real history rather than a purely invented alternative, which is exactly why students must know this timeline instead of guessing. Cebu City (option C) is incorrect; it is a major urban centre and historic port in the central Philippines, often called the country's second most important city, but it has never held national capital status. Davao City (option D) is incorrect; it is the largest city by land area on the southern island of Mindanao and an important economic hub, yet likewise never the seat of national government. A common exam trap is that students encountering 'Quezon City' in a history-linked passage assume it remains the capital today, when the correct modern answer is Manila. Revision takeaway: Manila is the Philippines' capital today and historically for most periods, while Quezon City held that status only briefly between 1948 and 1976.
