Which of these played the least influential role as a long-term cause of world war i? a) colonial disputes eliminate b) religious differences c) the drive for naval superiority d) ethnic tensions within the austria empire

While religions may have varied in Europe, they were not attributed to causing World War I. Military buildups and land disputes added to European tensions.

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 ! : )
