Answer: A.
Step-by-step explanation:
Voters elect members of the legislative branch occurs in both presidential and parliamentary governments. In a presidential system, voters directly elect members of the legislative branch (such as the U.S. Congress), while in a parliamentary system, voters elect members of parliament who then choose the head of government. However, in both systems, the power to elect representatives to the legislative branch ultimately lies with the voters. B is incorrect as the legislative branch does not select the head of government in presidential systems. C is only true for presidential systems, while in parliamentary systems, the leader of the executive branch is elected by members of parliament. D is also incorrect as the executive branch operates independently from the legislature only in presidential systems, while in parliamentary systems, the executive branch is accountable to the legislature.
