The correct answer is: a) 1881
The first complete census of Manipur was conducted in 1881. The census was conducted by the British government and was part of a larger effort to collect data on the population of India. The census found that the population of Manipur was 174,391. The census also collected data on the age, sex, religion, occupation, and literacy of the population.
The 1881 census was a significant event in the history of Manipur. It was the first time that the population of the state had been accurately counted. The data collected by the census was used to develop policies and programs to improve the lives of the people of Manipur.
The 1881 census was also significant because it was the first time that the people of Manipur had been classified as a separate ethnic group. This classification was important because it helped to legitimize the identity of the Manipuri people.
The 1881 census was a major undertaking and it is a valuable source of information about the history of Manipur. The data collected by the census is still used by researchers and historians today.
The other options are incorrect because they are not the years in which the first complete census of Manipur was conducted.
