The correct answer is B) a political response of the 1960s and 1970s.
The statement that describes the conservative movement is "a political response of the 1960s and 1970s."
The conservative movement initiated in the United States in 1960 until approximately 1970. The conservative people wanted to lower taxes. Let's remember that elevated taxes were necessary for other administrations to promote and support public programs aimed to help poor people like The Great Society program impulsed by Lyndon B. Johnson. So the conservative movement in America did not approve the idea of a government that had to spend too much and for that to happen, had to raise taxes.
