The Correct Option is B
Solution and Explanation
Step 1: Understanding the Question:
The Census of India is not finished in a single day. Enumerators visit households over many days across the whole country, so the actual counting work is spread over a period. The question asks what single date this whole spread of work is treated as belonging to.
Step 2: Key Formula or Approach:
Every census needs one fixed reference point in time so the count means the same thing everywhere. No births, deaths, or moves before or after that date should change the number. In India this reference point is called the census reference date.
Step 3: Detailed Explanation:
The reference date fixed for the Indian census is the sunrise of 1st March of the census year (a few states with harsh winters or floods, like Jammu and Kashmir or Assam, use an earlier reference date instead, but the reference point meant here, and used for most of the country, is March 1st).
Option (a), January 1st, is the reference date used by some other countries, not India.
Option (c), April 1st, is the start of the Indian financial year, not the census reference date.
Option (d), March 31st, is the end of the Indian financial year, again unrelated to the census count.
Step 4: Final Answer:
So even though the field work runs for weeks, every person counted is recorded as existing on 1st March of that census year.
\[ \boxed{\text{March 1st}} \]
