Answer:
c) Slovakia suffered economically.
Explanation:
Considering the available options in the question, one negative effect of the end of communism in Czechoslovakia is that "Slovakia suffered economically."
This is because, following the aftermath of the end of communism in Czechoslovakia, there were a lot of political changes including the eventual dissolution of the Czechslovakia nation in 1993.
This dissolution or break up into two nations, however, worsens the economic conditions of the two countries that came out of the Czechslovakia, which are both Slovakia and the Czech Republic.
Hence, in this case, the correct answer is Slovakia suffered economically.
