an important part of president nixons domestic policy was\ndétente.\npragmatism.\nnegotiation.\nrealpolitik.

Answer:

None of the above options are correct for Nixon's domestic policy. Detente was a foreign - policy approach related to easing Cold - War tensions with the Soviet Union and China. Pragmatism is a philosophical approach rather than a specific domestic policy. Negotiation is a general method and not a distinct domestic policy. Realpolitik is also more related to foreign - policy realignment based on national interests.

Brief Explanations:

Nixon's domestic policies included New Federalism (shifting power from the federal government to states), wage and price controls, and efforts in environmental protection and social welfare reform. The given options pertain more to foreign - policy or general concepts not specific to his domestic agenda.
