Final answer:
A bill can be introduced to the Georgia General Assembly only by a legislator, not by the governor, secretary of state, or any citizen. The correct answer is option D.
Step-by-step explanation:
In the Georgia General Assembly, a bill can only be introduced by a legislator. While constituents, interest groups, and even the governor can suggest or influence legislation, the actual process of introducing a bill must be done by a state representative or senator. This is because legislators are the elected officials who have been empowered to create and pass laws within the state's legislative framework. The governor has the power to sign or veto legislation but does not have the authority to introduce it in the General Assembly. The secretary of state of Georgia is responsible for maintaining state records and would not be involved in the legislative process of introducing bills.
