The correct answer is option 1, Executive. The executive branch of government is responsible for implementing and enforcing laws. They are in charge of carrying out the day-to-day operations of the government and ensuring that laws are put into practice. This includes making and enforcing regulations, overseeing government departments and agencies, and implementing policies and programs. The executive branch is led by the president or prime minister and their appointed officials, who are responsible for executing and administrating the laws passed by the legislature. While the legislature has the power to create laws, it is the executive branch that is responsible for actually putting them into action. Therefore, implementing laws is primarily the function of the executive branch.
