Final answer:
The dissolution of the Soviet Union(option d) was not the intended result of Mikhail Gorbachev's policy of glasnost. While the policy did lead to increased openness, it inadvertently set off a chain of events that contributed to the fall of the Soviet Union in 1991.
Step-by-step explanation:
The dissolution of the Soviet Union was not a (perhaps unintended) result of Mikhail Gorbachev's policy of glasnost. While glasnost did lead to an increased political openness and freedom of expression and it also posed challenges to the Communist Party's authority, the policy was aimed at reforming and saving the Soviet Union, not disbanding it. Gorbachev's reforms, including both glasnost and perestroika, intended to modernize the Soviet system, did lead to a series of events that would contribute to the ultimate fall of the Soviet Union, but this was not the direct intention of glasnost itself.
During the process of implementing glasnost, the policy of increased openness and transparency of government activities, many previously-suppressed individuals and groups began to express their discontent and demand changes. This newfound freedom included the right to criticize the government, which led to an atmosphere where the public and various republics of the Soviet Union started to push for greater autonomy and eventually independence. The eventual collapse of the Soviet Union in 1991, which marked the end of the Cold War, was a complex process influenced by both internal and external factors, with glasnost being just one of the contributing elements.
