According to Article 1, which areas are included in Pakistan?

Article 1 of the Constitution of Pakistan defines the territory of Pakistan. It states that Pakistan shall be a Federal Republic to be known as the Islamic Republic of Pakistan, and its territory shall comprise the Provinces, the Federal Capital (Islamabad), and such States and Territories as are or may be included in Pakistan, whether by accession or otherwise. Historically, this included Federally Administered Tribal Areas (FATA) which have since been merged with Khyber Pakhtunkhwa, but the foundational definition in Article 1 covers these broad categories.

• Provinces + Federal Capital + Tribal Areas (Correct): Article 1 broadly defines Pakistan's territory to include the provinces, the Federal Capital, and other territories, which historically encompassed tribal areas.
• Provinces only (Incorrect): This is an incomplete definition.
• Provinces + Gilgit-Baltistan only (Incorrect): While Gilgit-Baltistan is part of Pakistan, this option is not the comprehensive definition provided by Article 1.
• Provinces + FATA only (Incorrect): FATA was part of the "Tribal Areas" but this option is not as comprehensive as the correct one, especially considering the Federal Capital.
