Very recently, in which of the following countries have lakhs of people either suffered from severe famine/acute malnutrition or died due to starvation caused by war/ethnic conflicts?

This question refers to major humanitarian crises that have been widely reported due to severe famine, acute malnutrition, and deaths caused by ongoing conflicts and ethnic violence. Yemen has been embroiled in a devastating civil war since 2014, leading to one of the world's worst humanitarian crises. Millions have faced severe food insecurity, malnutrition, and famine-like conditions due to the conflict, blockades, and economic collapse. South Sudan gained independence in 2011 but has since been plagued by civil war and ethnic conflicts, which have caused widespread displacement, disrupted agriculture, and led to severe food shortages, acute malnutrition, and repeated declarations of famine in various parts of the country. The other options, while facing various challenges, have not experienced widespread famine/acute malnutrition on the same scale or directly caused by war/ethnic conflicts in the recent past as Yemen and South Sudan.
