Answer:
The answer is: letter D, He votes to elect officials to represent him in the government.
Step-by-step explanation:
Ancient Greece has a huge influence on the democracy of the USA, especially when it comes to the power of the people (state). Part of Greek culture was the replacement of their people in the government position through "peaceful means." Such means was the "election" whereby people were allowed to vote the candidate they see fit. In order to vote, the citizens needed to attend the assembly. From there, the voting takes place.
Just like the ancient Greeks, Mr. Sanchez is also doing the same activity of voting in order to elect officials that would represent him in the government. This means that he also has a voice and takes an active role in a democratic society.
Thus, this explains the answer.
