The correct answer is Somalia (option 4). Here`s why:

Option 1: Angola has indeed faced its share of civil strife and food shortages. However, it has not been in recent news for a severe famine, which makes it not the best answer.

Option 2: Costa Rica is renowned for its stability, peace, and development in contrast to the other options. Civil strife and food shortages are not significant issues compared to those of the other countries listed here.

Option 3: Ecuador, like Costa Rica, is generally stable. Although it struggles with poverty and inequality, it`s not recognized for decades of civil war or severe famine.

Option 4: Somalia has been facing civil wars, violence, and instability for several decades. Moreover, it has one of the world`s most severe humanitarian crises with repeated episodes of massive food shortage and famine, which regularly makes the news. Therefore, Somalia is the best answer among the options given.
