The correct answer is D. The results of the 1956 uprisings in Poland and Hungary differed in that Nikita Khrushchev responded with troops and tanks to the uprising in Hungary, but not in Poland.
Unlike what happened with the Poznan Protests against the government of the People's Republic of Poland, the Hungarian Revolution questioned the Stalinist style of government and, therefore, threatened the very nature of the pro-Soviet one-party regime. Thus, after announcing its willingness to negotiate the withdrawal of Soviet forces, the Politburo changed its mind and mobilized to crush the revolution. Taking advantage of the fact that the West was divided because of the Suez crisis, the Soviet army mobilized 31,550 soldiers and 1130 tanks and on November 4, 1956, it invaded Budapest and other regions of the country. The Hungarian resistance continued until November 10. More than 2,500 Hungarians and 722 Soviet soldiers perished in the conflict and some 200,000 Hungarians fled as refugees, mass arrests and accusations continued for months. By January 1957, the new government installed by the Soviets and led by Janos Kadar had suppressed all public opposition.
