In India, National Civil Services Day is celebrated to acknowledge the contribution of civil servants to public administration and nation building. On which date is National Civil Services Day observed each year?

Introduction / Context:
National Civil Services Day is an important observance in India that recognises the work of officers in the civil services, including the Indian Administrative Service and other allied services. The day is used to reflect on public administration reforms and to honour outstanding performers. Knowing its exact date is a common requirement in examinations related to Indian polity, governance, and general knowledge.

Given Data / Assumptions:

• The observance is National Civil Services Day, specifically for India.
• It is held every year on the same date.
• The question offers four possible dates in March and April.
• We must pick the date that correctly corresponds to this Indian observance.

Concept / Approach:
National Civil Services Day in India is celebrated on 21 April each year. The date honours the day in 1947 when Sardar Vallabhbhai Patel addressed probationers of the Administrative Service in Delhi, referring to them as the steel frame of India. The approach is to connect this historic speech with the date of the observance and to remember that it falls in April, not in March.

Step-by-Step Solution:
Step 1: Note that the question is about an Indian national observance, not a global United Nations day.Step 2: Recall that National Civil Services Day is linked to Sardar Patel's 1947 address and is observed on 21 April.Step 3: From the options, identify 21 April, which is option A.Step 4: Verify that the other dates either fall in March or correspond to different observances.Step 5: Choose 21 April as the correct answer.

Verification / Alternative check:
To verify your answer, recall that government of India events, awards for excellence in public administration, and conferences on governance are reported in the news every year around 21 April. Many exam oriented notes clearly state that National Civil Services Day is observed on 21 April to commemorate the historic guidance given by Sardar Vallabhbhai Patel to civil servants.

Why Other Options Are Wrong:
23 April is not designated as National Civil Services Day, although it may be associated with other minor observances or events.

21 March is far earlier in the year and is not connected with this particular Indian observance.

22 March is known internationally as World Water Day and within India it is not associated with civil services.

Common Pitfalls:
Students sometimes confuse the dates of different administrative or constitutional events, such as mistaking 21 April for a date close to Republic Day or Civil Services examination dates. Another common pitfall is mixing this day with international United Nations observances in late April. To avoid confusion, remember the simple link that civil servants are celebrated on 21 April in India, just as teachers are honoured on 5 September and doctors on 1 July. Creating such associations makes recall much easier.

Final Answer:
The correct date is 21 April.
