Which of the following is not the function of the government?

The function of the government is to manage and regulate the affairs of the state. While some functions of government may vary from country to country, some are generally agreed upon. These functions include building infrastructure like roads, bridges, canals, etc; providing education, maintaining relations with other states, defending the territory from external attack, and ensuring the welfare and security of its citizens. Therefore, providing all the material needs of all citizens is not a function of the government as it is practically impossible for any government to provide all the material needs of all citizens. While governments can provide some basic necessities like food, water, and shelter, citizens are responsible for their own personal material needs. Hence, "provision of all the material needs of all citizens" is not a function of the government.
