What interface does MapEntry implement?

Set
List
Queue
Map.Entry

The correct answer is: Map.Entry

This is because MapEntry represents a key-value pairing in a Map, so it makes sense that it would implement the Map.Entry interface. The other options are incorrect because Set does not represent key-value pairs, List and Queue do not have an association with Map, and they all do not fulfill the requirements for the MapEntry interface.
