Why list items need keys

Why should every item in a React Native FlatList have a stable, unique key?

A.Keys tell FlatList which images to cache in memory, so recycled rows scroll faster and do not reload their picturesB.Keys are required before list items can receive touch eventsC.Keys let React match items between renders, so it updates, reorders and keeps item state correctlyD.Keys are read out as accessibility labels by screen readers
