Answer:
The answer is B) An organized challenge to incumbents in the Republican Party by the most conservative wing of the Republican Party.
Explanation:
The Tea Party movement is a populist branch of conservative Republicans. It opposes government spending, taxation, and regulation. The organization believes that these are how the government infringes on Americans' personal liberties as outlined in the Constitution.
It was founded amid a groundswell of populist anger over government bail-outs of failing banks, insurers and auto companies following the economic meltdown of 2008.
