The a) is the only possible one. It is mere speculation if Startk senior activated any portal, and that Thor or Selvig told them, Thor was gone (and before that he never seen Tesseract) and Selvig... maybe, but unlikely. He was under influence from Loki, he wont tell them what he is about to do, right? And for Cap, from his perspective it seemed like Red Skull was vaporized by Tesseract and flying to the stars. he may not exactly tell them that he was teleported away.

You are cooking out of water :D
