Once across the bridge they can go back underground through downtown. It is similar to option B but I don't think B would get much support if it is going to run over top of Prince's Island at all.

I don't think that would be physically possible. The lower deck of the bridge has a clearance of 8'10". I don't know how tall a C-Train car is, but I know that I'm 6'1" and can stand comfortably inside one without banging my head and the platforms are a few feet off the ground, so they're definitely much taller than 9 feet.
With the way it's built, they wouldn't be able to lower the lower deck to increase the clearance either.
