The correct answer is: D. State.
Public pensions are a type of retirement plan that is funded by the government. They are typically available to government employees, such as teachers, firefighters, and police officers. Public pensions are designed to provide a secure retirement income for these workers.
Insurance companies do not provide public pensions. They provide private pensions, which are funded by employers and individuals. Employers may offer private pensions as a benefit to their employees. Individuals may also purchase private pensions on their own.
Individuals do not provide public pensions. They may contribute to private pensions, but public pensions are funded by the government.
The state is the entity that provides public pensions. The government sets the rules for public pensions, and it also collects the contributions from employers and employees. The state then invests these contributions and uses the earnings to pay out pensions to retirees.
Public pensions are a valuable benefit for government employees. They provide a secure retirement income that can help these workers maintain their standard of living after they retire.
