Which of the following is NOT a function of government?

Promoting trade is typically associated with economic activities and business functions rather than being a fundamental purpose of government. While governments may take measures to foster trade through regulation or partnership with businesses, it is not a core function like ensuring national security, providing services, or maintaining order. These core functions are essential for the stability and operation of society.

Ensuring national security involves protecting a country from external threats and maintaining the safety of its citizens. Providing services encompasses a wide range of public needs, such as education, healthcare, and infrastructure, which are crucial for citizens' well-being. Maintaining order refers to law enforcement and the establishment of laws and regulations that uphold societal norms. In contrast, promoting trade, while beneficial, falls outside the essential responsibilities that define the primary functions of government.
