-People should only be taxed by representatives whom they have elected.
In this passage, Jefferson states that the people should choose their representatives even though they might not make good choice about who should represent them. He believes that people should only be taxed by those they've chosen to represent them. Option A does not actually answer the question since it just says they choose their own representatives, not why. Option B and D are also wrong because he believes the representatives will not actually be qualified or have any experience.
