"Control" and "Destroy" are the indoctrination. "Synthesis" (I really don't think it should be called that) is not an option the catalyst-AI gives Shepard. Shepard Catalyst tells Shepard that organic and AI life cannot exist. If Shepard chooses "Destroy", all AI life (Reapers, Geth, EDI) will go away, but Catalyst says that your children will repeat the same mistakes and bring AI life back again. So in essence all Shepard accomplishes is that he/she becomes the "new" catalyst and will repeat the cycle all over again. Choosing "Control" is as everyone described earlier. Only the the third choice, the one where Shepard decides to take a "leap of faith" and believes that both forms of life can exist.
