15 August is celebrated as Independence Day in India and is also marked as the national liberation day of which of the following countries?

Introduction / Context:
This question tests knowledge of important national days across different countries, and invites you to connect India's Independence Day with a similar observance elsewhere. Many exams include comparative questions on which countries share the same independence or liberation dates, so this is a useful fact to remember.

Given Data / Assumptions:

• India celebrates its Independence Day on 15 August.
• The question asks which other country also observes 15 August as a national day of independence or liberation.
• Options include South Korea, Indonesia, China, Pakistan and Bangladesh.

Concept / Approach:
Countries often commemorate key historical events like independence or liberation from colonial or foreign rule. The approach here is:

• Recall which country celebrates its national independence or liberation day on 15 August.
• Use elimination by linking other countries in the options to their correct national day dates.
• Select the option whose national day matches 15 August.

Step-by-Step Solution:
Step 1: Remember that India celebrates Independence Day every year on 15 August. Step 2: Recall that South Korea celebrates a major national day called Liberation Day, marking the end of Japanese rule, on 15 August. Step 3: Examine the other options and recall their national day dates: Indonesia celebrates independence on 17 August, Pakistan on 14 August, and China on 1 October. Step 4: Bangladesh celebrates its Independence Day on 26 March and Victory Day in December, not on 15 August. Step 5: Conclude that South Korea is the country that, like India, observes a national day on 15 August.

Verification / Alternative check:
You can verify this by checking standard general knowledge references or country profiles which list national days. These show that South Korea observes 15 August as Liberation Day, commemorating the end of colonial rule. Cross checking this information with reliable sources makes it clear that South Korea is the correct match to the date 15 August among the options given.

Why Other Options Are Wrong:
Indonesia: Celebrates its independence day on 17 August, which is close but not the same as 15 August. China: Marks its National Day on 1 October, not in August. Pakistan: Celebrates its independence day on 14 August, one day before India. Bangladesh: Has independence and victory commemorations on dates in March and December, not on 15 August.

Common Pitfalls:
A common mistake is to choose Pakistan because its independence day falls so close to that of India. Some candidates also guess Indonesia due to confusion between 15 and 17 August. Mixing up these similar dates is easy if you memorise them vaguely. A better strategy is to create a small comparison list in your notes where you group countries by independence dates, emphasising that South Korea and India both highlight 15 August in their national calendars, but for different historical reasons.

Final Answer:
Besides India, the country that has a national day on 15 August is South Korea.
