In world history and geography, the Forbidden City is a famous former imperial palace complex; in this general knowledge question you must identify in which modern country the Forbidden City is located.

Introduction / Context:
The Forbidden City is one of the most iconic palace complexes in the world, often referenced in world history, art, and tourism GK. It served as the seat of imperial power for centuries, so exam questions frequently ask candidates to associate it with the correct country. Knowing its location is a basic requirement for international GK and heritage related questions.

Given Data / Assumptions:
The Forbidden City is described as a historic complex known globally.
The options include four Asian countries: Mongolia, Nepal, Bhutan, and China.
We assume the question refers to the well known Forbidden City in East Asia that appears in history textbooks and travel references.

Concept / Approach:
This is a pure recall question based on world heritage and historical capitals. The Forbidden City is the former imperial palace of the Ming and Qing dynasties and is located in the heart of Beijing. Beijing is the capital city of China. Therefore, correctly answering the question requires linking the monument to Beijing and then to the country, China.

Step-by-Step Solution:
Step 1: Recall that the Forbidden City is a large walled palace complex used by Chinese emperors. Step 2: Remember that it is located in Beijing, which is the present capital of China. Step 3: Look at the options and locate China among Mongolia, Nepal, Bhutan, and China. Step 4: Eliminate other countries that do not have Beijing as a city and that are not historically linked to the Forbidden City. Step 5: Select China as the correct country.

Verification / Alternative check:
Any standard world atlas, encyclopedia, or school level history book confirms that the Forbidden City, now a museum complex officially called the Palace Museum, is in central Beijing. Beijing is in northern China. Tourism promotions and UNESCO World Heritage lists also describe it as a major attraction in China. Since all these independent references agree, we can be confident that China is the only valid answer.

Why Other Options Are Wrong:
Mongolia: Historically linked with the Mongol Empire, but the Forbidden City is not located in Ulaanbaatar or any Mongolian city.
Nepal: Known for the Himalayas and cities like Kathmandu and Pokhara, but it does not contain the Forbidden City.
Bhutan: A Himalayan kingdom with monasteries and fortresses, yet it has no structure known as the Forbidden City.

Common Pitfalls:
Some candidates confuse Mongol history with Chinese imperial history and wrongly choose Mongolia. Others may simply guess among smaller countries, forgetting that Beijing is in China. To avoid such mistakes, always connect the Forbidden City with Beijing and then clearly with China in your memory map of world capitals and monuments.

Final Answer:
The Forbidden City is located in: China.
