I believe the answer is D :)
The correct answer to this open question is the following.
Congressman has to respond to the Big Pizza Lobby taking these considerations in mind.
Congressman has to realize the impact of the presence of this big "company" in the market. Not only for other industries that cannot compete with this huge company but the impact it has on consumers.
The congressman would propose the kind of bill that benefits free trade, competence, and benefits consumers in a free market.
The big company is not going to stay "arms-folded." The company is going to hire lobbyists to negotiate with congressmen in order to promote its particular agendas and personal interests.
Of course, the big company wants to change the rules against it, and modify them to facilitate their interests. The negotiations can make legislators doubt or rethink a regulation. That is when Congressman has to think to support the interests of citizens, who were the ones who took him/her to office in the elections. So congressmen serve the people, not large companies.
D. were similar in a few ways and different in the other
