In the highly acclaimed episode "The Trouble With Tribbles," one of the space visitors is revealed to be a Klingon spy. What's their name?

All of the above options were spies in Star Trek, however, in the episode "The Trouble with Tribbles", Arne Darvin was the Klingon spy. He poisoned the quadrotriticale so the Klingons would occupy the Sherman's Planet.
