Cambodia is a Southeast Asian country known for the Angkor Wat temple complex. What is the capital city of Cambodia?

Introduction / Context:
This question tests your knowledge of Southeast Asian capitals by asking for the capital city of Cambodia. Cambodia is famous for its ancient temples, especially Angkor Wat, and for its recent history and development. The capital city, Phnom Penh, is the main political and economic center of the country. Knowing that Phnom Penh is the capital of Cambodia is a standard requirement in many general knowledge and competitive examinations.

Given Data / Assumptions:

The country mentioned is Cambodia in Southeast Asia.
You must choose its capital city from four options.
The options are Phnom Penh, Hanoi, Lamur, and Bangkok.
Hanoi and Bangkok are well known capitals of other Southeast Asian countries, while Lamur appears as a distractor name.

Concept / Approach:
The main concept is correctly matching Cambodia with Phnom Penh. Phnom Penh lies at the confluence of the Mekong and Tonle Sap rivers and serves as the center of Cambodia's government and urban life. Hanoi is the capital of Vietnam, and Bangkok is the capital of Thailand. Lamur does not correspond to a real capital city in this context, so it functions as a distractor. By understanding the regional grouping of countries and their capitals, you can confidently select Phnom Penh as the correct answer.

Step-by-Step Solution:
Step 1: Identify Cambodia as the country for which you need to find the capital.Step 2: Recall that Phnom Penh is the capital and a major city located on important rivers in Cambodia.Step 3: Recognize that Hanoi is associated with Vietnam and Bangkok with Thailand.Step 4: Note that Lamur does not correspond to a commonly known capital city in Southeast Asia.Step 5: Eliminate Hanoi, Lamur, and Bangkok, and choose Phnom Penh as the correct answer.

Verification / Alternative check:
Maps of Southeast Asia show Cambodia with Phnom Penh marked as its capital. Travel and history resources about Cambodia describe Phnom Penh as the gateway to Angkor Wat and other cultural sites, as well as the seat of government. When you look up Vietnam, you see Hanoi listed as its capital, and for Thailand you see Bangkok. None of these references present Lamur as a capital. This consistent mapping confirms that Phnom Penh is the capital of Cambodia.

Why Other Options Are Wrong:
Hanoi is the capital of Vietnam, a neighboring country to Cambodia, but it does not serve as Cambodia's capital. Bangkok is the capital of Thailand, another neighbor in the region. Lamur, as given in the options, does not match any recognized national capital in Southeast Asia and appears only as a distractor. Therefore, all three alternative options are wrong for this question, and only Phnom Penh correctly answers it.

Common Pitfalls:
Because several Southeast Asian countries are close together and share some cultural features, learners may confuse capitals like Phnom Penh, Hanoi, Bangkok, and Vientiane. Another common issue is being misled by unfamiliar names like Lamur and thinking that they might represent lesser known capitals. A good strategy is to draw a simple regional map and label each country with its capital, reinforcing this knowledge through repeated practice. Associating Cambodia with the Angkor temples and Phnom Penh with rivers and urban life can help fix this pair in memory.

Final Answer:
The capital city of Cambodia is Phnom Penh.
