What is the capital of Bangladesh?

The correct answer is Dhaka, the capital and largest city of Bangladesh, situated on the banks of the Buriganga River in the central part of the country. Dhaka has served as the political and administrative capital since Bangladesh's independence in 1971, continuing an administrative importance it held even earlier as the capital of East Pakistan and, briefly in Mughal history, as the provincial capital of Bengal under the name Jahangirnagar. Chittagong is incorrect because although it is Bangladesh's second-largest city and its principal sea port, handling the bulk of the country's maritime trade, it has never functioned as the national capital. Khulna is incorrect because it is a significant industrial and port city in the southwest, close to the Sundarbans, but it holds only divisional administrative status, not national capital status. Sylhet is incorrect because it is an important northeastern city known for tea gardens and a large diaspora population abroad, but like Khulna it is a divisional headquarters rather than the seat of the national government. A common exam confusion arises because Chittagong's economic weight as the chief port sometimes leads students to assume it must also be the capital, similar to how Mumbai is sometimes mistakenly guessed as India's capital because of its economic prominence. The revision takeaway is to fix Dhaka firmly as the political capital, Chittagong as the port and trade hub, and Khulna and Sylhet as important but non-capital divisional cities, ensuring the four are never confused in an objective question.
