In India, Air Force Day is celebrated on which date to commemorate the establishment of the Indian Air Force?

Introduction / Context:
India celebrates several defence related days to honour its armed forces, such as Army Day, Navy Day, and Air Force Day. Knowing the exact dates of these observances is a basic requirement in general knowledge for defence, civil services, and other competitive exams. Air Force Day marks the anniversary of the official establishment of the Indian Air Force and showcases its role in safeguarding national airspace.

Given Data / Assumptions:

• The question asks for the date on which Air Force Day is celebrated in India.
• Four closely packed dates in October are provided as options.
• The context is clearly national defence and commemorative events.
• We assume the candidate is expected to recall the standard date used every year for Air Force Day celebrations.

Concept / Approach:
In India, Air Force Day is celebrated on 8 October every year. This date marks the official formation of the Indian Air Force in the early nineteen thirties during the British period, after which the service grew into a modern aerial defence force. The approach is to memorise a set of key defence observance dates: 15 January for Army Day, 4 December for Navy Day, and 8 October for Air Force Day. Linking each date to the respective force helps in quick recall during exams.

Step-by-Step Solution:
Step 1: Recognise that the observance asked in the question is Air Force Day in India. Step 2: Recall that the Indian Air Force was formally established in October and that its anniversary is celebrated annually. Step 3: Remember that the exact date fixed for this celebration is 8 October. Step 4: Compare this mental recall with the options that list 9, 10, 11, and 8 October. Step 5: Select option D, 8 October, as it correctly matches the official Air Force Day in India.

Verification / Alternative check:
Verification is straightforward because newspapers, television channels, and official social media handles of the Indian Air Force highlight Air Force Day celebrations every year on 8 October. Defence oriented exam books and static GK notes also list this date among important national days. Cross checking with reliable sources such as government websites and reputable exam preparation materials confirms that 8 October is the accepted answer.

Why Other Options Are Wrong:
Option A, 10 October, is not the date on which Air Force Day is officially celebrated in India and is therefore incorrect.
Option B, 11 October, has no special link with Air Force Day and is only a distractor in this context.
Option C, 9 October, is close to the correct date and may trap candidates who only remember that the day falls in early October, but it is not the precise date.

Common Pitfalls:
Candidates may mix up Air Force Day with other October observances or may misremember the date as 9 or 10 October due to proximity. Another pitfall is confusing Army Day, Navy Day, and Air Force Day dates, especially under exam pressure. Creating a small three line note that lists 15 January for Army Day, 4 December for Navy Day, and 8 October for Air Force Day is a simple yet effective method to avoid such errors.

Final Answer:
In India, Air Force Day is celebrated every year on 8 October.
