The first census specifically for Mizoram was conducted in the year:

1951
1971
1981
2001

The correct answer is: b) 1971

Mizoram was a part of Assam before it became a separate state in 1972. Therefore, the first census specifically for Mizoram was conducted in 1971.

The other options are incorrect because:

  • Option a) is incorrect because the first census of India was conducted in 1872.
  • Option c) is incorrect because the first census of Assam was conducted in 1881.
  • Option d) is incorrect because the first census of India after Mizoram became a separate state was conducted in 1981.
