What was the main reason the Soviet Union crumbled in the 1980s?

Question

A. Glasnost led to rebellion against communist rule around the world.
B. The Soviet economy could not match U.S. military spending while meeting citizens' demand for consumer goods.
C. Policies introduced by Mikhail Gorbachev resulted in the Soviet Union losing its main source of income.
D. The United States convinced Soviet leaders to abandon communist economic policies.

Can someone please explain to me why B is the correct answer and A is not?

Answer 1

B is part of the reason the Soviet empire collapsed. The United States embarked on a massive arms build-up in competition with the Soviet Union. The effort for the Soviets to keep up caused economic problems within the USSR. A is also part of the answer. Whomever wrote your "quiz" and school program obviously thinks B is the most important part of the picture. In truth, it's only part of the story. But only one answer will be correct, according to the algorithm that checks your answers.
