Answer: D. Speaker 4.

Through the representative system, elected officials or leaders tend to advocate for the needs and desires of the individuals that elected them, and to develop projects and policies that benefit societies as a whole according to its party's values and beliefs.
From all the choices, speaker 4 is the one that is most likely to feel represented in the U.S. government because the Republican Party has been for decades one of the two major political parties in the nation (the other is the Democratic Party), and it is also the party that has a majority in the government nowadays, thus this party have more chance of enacting laws or policies that favor their values, and the speaker's values too.
