28. Which of the following individuals was the last president of the Soviet Union before it dissolved?

Answer: C

Explanation:

Mikhail Gorbachev was the last president of the Soviet Union before it dissolved.

Mikhail Gorbachev served as the final president of the Soviet Union, overseeing significant political and economic reforms that ultimately led to the dissolution of the state in 1991.

A) Yuri Androp

Yuri Andropov was the General Secretary of the Communist Party and held power prior to Gorbachev, but he never served as president. His tenure was short-lived, and he did not lead the country during its transition period.

B) Leonid Brezhnev

Leonid Brezhnev was a prominent leader of the Soviet Union known for his long tenure as General Secretary, but he passed away in 1982, well before the dissolution of the Soviet Union and the presidency held by Gorbachev.

C) Mikhail Gorbachev

Mikhail Gorbachev was indeed the last president of the Soviet Union, serving from 1990 until the dissolution in 1991. His policies of glasnost (openness) and perestroika (restructuring) played critical roles in transforming Soviet society and politics.

D) Nikita Khrushchev

Nikita Khrushchev was a significant figure in Soviet history, known for his leadership during the Cold War and the Cuban Missile Crisis. However, he was removed from power in 1964, long before Gorbachev's presidency and the eventual dissolution of the Soviet Union.

Conclusion

The correct answer, Mikhail Gorbachev, is definitive as he was the last president overseeing the Soviet Union's final days and its transformation. All other options represent leaders who either predated Gorbachev or did not hold the title of president, thus making them incorrect choices in the context of the question.
