me- will give 16 points and brainliest answer
why did soviet leader mikhail gorbachev introduce economic and political reforms?
a. to establish his dominance by bringing about changes
b. to earn the respect of the united states and its allies
c. to appeal to the dissatisfied, multiethnic population of the soviet union
d. to obtain greater funds from international markets at lower interest rates
e. to encourage men to join the red army

The correct answer is:

Gorbachev was not trying "to establish his dominance," as the other answer here had suggested.  When Gorbachev came into leadership in the USSR, the Soviet economy was struggling and there were dissidents across the spectrum of the country who called out for reforms and changes.  

In 1985, Mikhail Gorbachev proposed policies of perestroika (restructuring) and glasnost (openness) in the Soviet Union.  Perestroika meant allowing some measure of private enterprise in the Soviet Union.  Glasnost meant allowing a bit of freedom in regard to speech and publication.
