Which allows you to look up an object using another object?

Map
Set
List
Queue

The correct answer is: Map

A Map is an abstract data type that stores key-value pairs and allows you to retrieve a value using its corresponding key. This is useful when you need to quickly search for a specific value and know its corresponding key. Sets do not have key-value pairs and are mainly used for membership checking. Lists and Queues do not allow you to search for an object by using another object. Therefore, the most appropriate answer is Map.
