It should be all of them.
Just remember in Java we can define our own classes type and give them whatever name we can think of. Sock is-a(n) Object because it extends/inherits from Object Class. Chocolate Class is-a Object. A collection of Amazon Gift Cards is also an Object since a Gift Card Type is-a child of the Object Super-class.
In short *All Java Class Types * inherit their properties from the Object Class.
In return Objects of the same type can be grouped together using Collections (*Lists, Sets, Maps or Queues *).
In Collection<T> T is just a placeholder and any child of Object Class can be inserted in between the diamond brackets.
