b. a decision made by all registered voters to change a government program.
c. the annual review of a government’s plans to spend taxpayers' money.
d. a forum where citizens can debate the merits of a government proposal.

I believe the answer is: A.a course of action the government takes in response to an issue or problem

The purpose of the creation of public policy is to address the concern of citizens regarding the issue or problem. Public policy is created by the executive branch of the government and can be found in multiple sectors, including health, crimes, social security, etc.
