Which of the following is an example of indirect influence on government officials?

An example of indirect influence on government officials is organizing a voter registration drive. This action does not directly engage with government officials or attempt to persuade them on specific legislation or policies. Instead, it aims to increase civic participation and voter turnout, which can, in turn, indirectly affect policy decisions and the priorities of elected officials. By empowering more citizens to vote, the drive influences the political landscape and the officials who are chosen, creating a ripple effect that can change the composition of government and public opinion.

Meeting with legislators and writing a legal brief are more direct efforts to influence officials by engaging them in discussions or providing legal arguments regarding specific issues. Conducting a survey could provide insights into public opinion; however, it doesn't actively mobilize voters or alter the political environment as a voter registration drive does.
