Which of the following software is best suitable for keeping records during national population census?

The best software for keeping records during national population census is a database. This is because a database is specifically designed for managing large amounts of structured data and provides powerful tools for data input, storage, retrieval, and analysis. With a database, census data can be organized in a systematic and meaningful way, making it easier to manage, update and extract relevant information when needed. Word processing software is primarily used for creating and editing text-based documents, while spreadsheets are used for numerical calculations and data analysis. Graphics software is used for creating visual content such as images and charts. While all of these software types may be used in the census process, a database is the most suitable option for managing large and complex datasets.
