Final answer:
Although the question's choices don't match the references provided, the seven African states which are likely considered most neglected based on the given context include the Democratic Republic of the Congo, South Sudan, Sudan, and the Central African Republic, among others facing similar challenges.
Step-by-step explanation:
The seven African states identified by the Norwegian Refugee Council as the most neglected in their 2020 report are not explicitly listed in the information provided. However, based on the context clues from the excerpts, we can infer that the countries likely to be on the list include those with significant refugee crises, widespread poverty, or political instability. For instance, the Democratic Republic of the Congo is repeatedly mentioned due to its low income, corruption, and political problems. Countries like South Sudan and Sudan are highlighted due to their crises, including refugees fleeing violence in Darfur and South Sudan's breakaway to independence. The Central African Republic is also named in the context of refugee crises and poverty.
It's important to note that countries such as Afghanistan, Yemen, and Syria, while they have significant issues, are not African states and therefore would not be on this particular list for African countries, even though they may appear as part of broader global indices of neglected crises or low-income nations.
