The correct answer is C. To meet with constituents in Washington DC and in the district.
Explanation:
In the U.S. government system, the national government level is connected with the local government level including citizens of all states. An example of this is that constituents (individuals who vote) of all states are informed about the actions of national entities such as the House of Representatives and this entity integrates members from different states.
In the quote presented, the House representative Mike Honda refers to the role of House of Representatives to "meet with people who live in our states" who are the constituents and in this way keep them informed about the actions of the national House of Representatives "tell them about what is happening in government". According to this, the duty Honda is referring to is "To meet with constituents in Washington DC an in the district."
