From the words lettered A to D, choose the word that best completes each of the following sentences. 

Unfortunately, corruption is the _______ of most African countries. 

Answer Details

The sentence suggests that the word to be selected should describe what is the cause of the problem in African countries. "Venom" refers to poisonous substances, which is not relevant to the sentence's context. "Bane" means a cause of great distress or annoyance, which is an appropriate word for the sentence because it means the root of the problem. "Disaster" refers to a sudden and widespread event that causes significant damage or loss of life, which is not appropriate for the context of the sentence. "Backbone" means the most substantial part of something, but it is not the appropriate word to complete the sentence. Therefore, the correct answer is "bane." It fits the sentence's context and means the root cause of a problem.
