Consider a Kripke structure with AP$=\{$receive$,$send,result$\}$ that can receive messages, send messages, and give a result.

One of the requirements of this Kripke structure is described using the following LTL formula:

GFreceive$$GFresult

Which one of the following informal requirements is most accurately described by this formula?

The system produces infinitely many results.

Whenever the system receives a message, then it eventually produces a result.

If eventually the system always receives messages, then it eventually always produces results.

If the system receives infinitely many messages, it produces infinitely many results.
