In South Asian geography, Bangladesh is a densely populated country bordering India and Myanmar. What is the capital city of Bangladesh?

Introduction / Context:
This question covers South Asian geography by asking for the capital city of Bangladesh. Capital cities are important to remember because they serve as political, administrative, and often economic centers of their countries. Bangladesh is an important nation in the region, and its capital city, Dhaka, is frequently mentioned in news, economics, and international relations. Knowing this country capital pair is valuable for school exams and competitive tests.

Given Data / Assumptions:

The country mentioned is Bangladesh in South Asia.
You are asked to identify its capital city from four options.
The options are Dhaka, Chittagong, Khulna, and Sylhet, all of which are real cities in Bangladesh.
Only one of these options is the actual national capital; the others are major regional cities.

Concept / Approach:
Bangladesh is a South Asian country with several large and important cities. Dhaka is the capital and largest city, serving as the center of government, finance, and culture. Chittagong is a major port city and an industrial hub, Khulna is an important city in the southwest, and Sylhet is known for tea gardens and remittances from overseas communities. To answer the question correctly, you must recall that Dhaka, not the other cities, hosts national government institutions and foreign embassies, which defines it as the capital city.

Step-by-Step Solution:
Step 1: Focus on the country name in the question, which is Bangladesh.Step 2: Recall that Dhaka is widely recognized as the capital and largest city of Bangladesh.Step 3: Consider the roles of the other cities: Chittagong as a port city, Khulna and Sylhet as regional centers, none of which host the national government.Step 4: Eliminate Chittagong, Khulna, and Sylhet because they are not the official capital.Step 5: Select Dhaka as the correct answer since it alone matches the definition of the capital of Bangladesh.

Verification / Alternative check:
Verification is simple using any reliable map, geography book, or government website. Bangladesh is clearly labeled with Dhaka as its capital. News reports about Bangladeshi politics, economics, and international visits regularly refer to Dhaka as the place where government meetings and diplomatic events occur. Chittagong, Khulna, and Sylhet are mentioned as major cities, but never as the capital. This consistent usage across many sources confirms that Dhaka is the correct capital of Bangladesh.

Why Other Options Are Wrong:
Chittagong is an important port on the Bay of Bengal and a major commercial and industrial center, but it is not the political capital. Khulna is a significant urban area in the southwest, while Sylhet is famous for tea plantations and diaspora connections. Neither Khulna nor Sylhet houses the national parliament or presidential offices. Therefore, all three are incorrect as answers to this question, and only Dhaka qualifies as the national capital.

Common Pitfalls:
Students sometimes get confused because multiple cities in a country are well known. They may assume that the largest port or the most talked about city in the media is the capital. In the case of Bangladesh, both Dhaka and Chittagong are well known, leading to possible confusion. A good strategy is to create a mental map of each country that clearly links it with one recognized capital city. Revising lists of capitals and using practice questions reduces the chance of mixing up cities within the same country.

Final Answer:
The capital city of Bangladesh is Dhaka.
