Gorbachev's economic policy was known as

A.
brinksmanship.

B.
INF.

C.
perestroika.

D.
START.

C. perestroika.

C. perestroika.

The correct answer is C. perestroika.

To arrive at this answer, it is helpful to have some background knowledge. Perestroika was a policy introduced by Mikhail Gorbachev, the General Secretary of the Communist Party of the Soviet Union, in the mid-1980s. The aim of perestroika was to reform and restructure the Soviet economy, which was facing various challenges such as inefficiency, corruption, and stagnation.

To find the answer to this question, you could use various strategies. One effective method is to eliminate the incorrect options, in this case, options A, B, and D:

Option A, "brinksmanship," refers to a strategy where one party pushes the other to the brink of disaster to achieve a favorable outcome. This strategy is mostly associated with international relations or foreign policy and does not relate to Gorbachev's economic policy.

Option B, "INF," stands for Intermediate-Range Nuclear Forces Treaty. This treaty was an arms control agreement signed by the United States and the Soviet Union, aiming to eliminate intermediate-range and shorter-range missiles. It is not related to Gorbachev's economic policy.

Option D, "START," stands for Strategic Arms Reduction Treaty. This treaty was another arms control agreement signed between the United States and the Soviet Union, focusing on reducing their strategic nuclear weapons arsenals. Again, it is unrelated to Gorbachev's economic policy.

By process of elimination, the correct answer is C, "perestroika." Perestroika was Gorbachev's economic policy aimed at reforming and restructuring the Soviet economy.
