When it comes to trusting the Catalyst it is important to remember that it is an unchained AI, which means that regardless of how it got there (take note of that qualifier Dreman) it is now an intelligent life form with a basic hierarchy of goals/needs. The top of that "pyramid", above completing any missions, regardless of who came up with it is self-preservation. Therefore if lying to make the option where it survives seem more enticing, then of course it will lie.
The proof that is an unchained AI, is that a chained AI lacks the ability to make complex decisions, it is essentially a VI with a much stronger computation power for achieving direct commands that are given to it. As a result, a chained AI would have been forced to terminate if its creators said no to its solution, thus a chained AI would have a kill-switch.
That considered, when one looks at the possible options, and examines long term effects looking at what the Catalyst doesn't say, drawing conclusions with simple logic and evidence from previous events, then the options look quite different.
For destroy, all that is apparently destroyed are the relays, probably because they are unable to withstand the force of the blast from the signal being sent through them, as well as the "minds" of the Reapers and apparently EDI and the Geth. The evidence of this is that ships do continue flying (in spite of the claim by the Catalyst), and Shepard apparently breathing at the end.
For Control, Shepard essentially becomes what David Archer was for the Geth in Overlord, except this time there is no ability to turn it off. While Shepard does have a stronger personality then David, the whispers of 300,000,000 Reapers over time will eventually drive him bananas leading a result that is likely not good.
For Synthesis, if the Catalyst is not lying about the impact of the DNA-like structure in combining minds (synthetics gain understanding) than the impact of those 300,000,000 Reapers is once again felt, this time on everything, and as the Catalyst is a major part of their thoughts, it is free to continue acting and influencing, thus a long-term result of bad things happening. EDI speaking at the end is evidence of the possibility of that.
Even if I'm wrong about the possible consequences of Synthesis there is still the Shepard making a decision for everything in spite of a lack of consent, informed or otherwise.
Even without those possibilies I chose destroy, because Shepard needs to find Tali.
