The correct answer is: A comprehensive database of residents.
The National Population Register (NPR) is a register of all usual residents in India. It is being created by the Ministry of Home Affairs (MHA) under the provisions of the Citizenship Act, 1955. The NPR will be a comprehensive database of residents of India, including their demographic and biometric information.
The NPR is being linked to the Census to create a more comprehensive database of residents. The Census is a decennial survey of the population of India. It provides information on the population size, distribution, and characteristics of the population. The NPR will be used to update the Census data and to create a more comprehensive database of residents.
The NPR will be used for a variety of purposes, including:
- Providing a basis for planning and implementing development programs
- Ensuring the effective delivery of government services
- Facilitating the implementation of welfare programs
- Preventing and combating crime
- Maintaining national security
The NPR is a voluntary exercise. However, it is important for all residents of India to register with the NPR. The NPR will help the government to better understand the population and to provide better services to the people.
The other options are incorrect because:
- Aadhaar-based biometric identification is a separate program that is being implemented by the Unique Identification Authority of India (UIDAI).
- Ration card distribution is a government program that provides subsidized food grains to eligible households.
- Voter ID updation is a process that is being carried out by the Election Commission of India to update the voter rolls.
