Given the options (and I still agree with my earlier post and Greebo's answer of "none of the above, replace your soffit with a vented version"), I'll go with option B.
Some other thoughts:
- Get a good seal between the vent and your existing soffit, which would won't be able to do with your first or last option.
- Make sure there's a screen of some kind in those vents to keep out the bugs, bees, and anything else that would enjoy making a home in your attic. This is why I suggest you get a good seal to the soffit.
- Make sure the insulation is not touching the roof and that there's a clear path for the air to flow from the soffit to the ridge vent.
- Finally, if you can get a plastic soffit vent, I'd go for that. You'll reduce the risk of corrosion and it will blend in better.
I think you've answered your own question, you've got the best compromise if you MUST go through the soffit.

It's just friction-fit, probably, if there are no fasteners present. The metal just presses outward with a little spring tension. You'd lift the new on up into the soffit cavity through the gap, then gently pull it down into position, maybe using a short wire hook.
I suppose you could install it upside-down on the surface, but you'd have to use some small screws. They'd need to be pre-drilled to avoid blowing out the edge of the gap. Won't look as nice, either.
