I'm going to vote by my logic and not by my experience. Since this is really my first time doing salt =)
Option B would be my vote.
All water passes through the sock(s),skimmer and refugium. So all water being pumped back into the display has been "treated." It will also be easier down the road if you decide to run reactors.

I'd say A. Admittedly, my sump is similar to B, but that's only due to the tight configuration space I had in my stand.
The main problem with B is the water movement may be too fast to create a great breeding location for pod's in the refugium. With option A, you can limit the amount of water that comes into that side via a ball valve as you don't want too much water movement. Plus even in b, not everything actually passes through the skimmer anyways, so it's not like you will be skimmed anyways. If you are concerned with excess waste getting back into the return, then you can put a filter (sponge, etc) between the refugium and the return.

I'll share my design which is a breed of both A & B (in function perhaps not in design);
My setup that I am currently working on will have the drains in the first chamber on the left (no socks) which will also house my skimmer, next section will be fuge, then last one will house the return pump. No bubble traps because my drain will run at full siphon & pipe outlet will be submerged.
I am redirecting my skimmer outlet to the last chamber to cut down flow on the refugium also so that the skimmer does not skim the refugium water. I mainly just want the fuge for copepod population.
Redirecting the skimmer alleviates the issue of too much flow to the fuge, this is how;
if my return pump is pushing 500 gph at the return nozzle, my skimmer (euroreef rs-80) has a pump that moves 325 gph, considering that this flow is directed past the fuge my fuge will only get 175 gph. If this is too low or too high I can easily adjust the return pump to the desired flow thus adjusting the fuge flow since the skimmer rate is static.

That's exactly what I did on my frag tanks. It seems to work well.

Would a sponge block the pods from entering the display from the fuge?

Exactly. If you leave the socks in for a week, it's just somewhere for stuff to rot.

Oh, that's how I roll with my fw tanks. No socks for me!

Ok. I think that idea works for me. Don't know if I mentioned it, but a fella on RC suggesting feeding the fuge with a part of the sump return in the middle via a split in the return line. Thought that was a slick idea too

Hmm. Looks like Jim has 2 votes for B, and one for A. 
I like B better, mostly because it is hard to keep the flow between left/right balanced,
and a fuge needs some flow. But it really depends on the fuge flow you want.
If space is critical, you may not need the first bubble trap on B. You essentially have two there.

I plan on keeping mine real simple which is along the lines of your "A" diagram except without all the baffles. I actually only have one wall to separate the fuge and the rest of the sump where the skimmer, heater, etc., reside. My drains will be T'd off so I can control how much of the drain flow goes to the fuge while the rest goes to the sump. Optionally, I may have it set up so that if I want to use a filter sock to 'polish' the water for visitors, I have that option.

I like A with modifications. The mod I'd make is to supply the fuge with water from the return. Have all the OF water go to a area for socks. As per denzil's post, it's so you can polish the water. Most of the time you'd be sockless but when cleaning/disturbing crud in the tank you can sock up and get rid of it all. Leave the socks in for 24hrs.
With fuge fed from the return you can easily control flow and it makes drain plumbing simpler. Return water is not fully clean water, just cleaner than tank water. It should have lots of nutrition for the fuge. With low flow in the fuge you probably don't need the bubble trap on the fuge side.
