One of the first amendments added after the bill of rights protected a) all laws established by individual states b) all laws established by the federal government c) states from being sued by citizens of other states d) states from being sued by the federal government

C. states from being sued by citizens of other states (i think)

i believe the correct answer is option b. most eastern european nations joined nato.

though i could be wrong, option d. the eastern european nations were granted complete independence, would be another choice.

hope this ! : )
