Not only besides RH or LH, you need to determine swing direction. Trust me, this needs to be agreed upon. When I built the additional room onto my house, I thought 84 Lumber understood the direction of door swing and they didn't. There is left inswing, right inswing, left outswing, and right outswing.
The door handle on my exterior door is on the right-hand side, but it is considered a left-hand outswing. Whereas my front door swings in, and the handle is on the right hand side so it is considered a right-hand inswing. Make sure you know what you are buying before you spend the money!
I like B, because the most critical jamb is the hinge side. Once its plumb, with shims behind the hinges, I rout the hinges in place with templates.
The other 2 jambs are "loose" until the door is hung. Then, with a helper, the gap around the latch side is dialed in, starting at the latch.
The top jamb is done last and isn't as critical, structurally, as the other 2.

If it is a split jamb it will not matter it will gauge itself to the wall thickness. If it is not, and you have an older home with 3 5/8" studs circa 1950-60's with 1/2 sheetrock, you will need the wider jamb. If it is a newer home, you may be able to go with the narrower jamb.
The biggest downside to a smaller jamb, is there may be a gap that can occur at the point where the trim meets the jamb. It can be caulked is it happens. This is still unlikely though since the trim has a relief to allow it to bridge over some unevenness in the assembly.
The biggest downside of the wider jamb is the reverse, a gap at the wall to the trim, but it will only happen at the corners, unless you force it back, which will then open the joint.
I would go with the wider jamb without seeing the conditions, if the walls are out of plumb a little you can use the extra width to tweak the jamb into plumb without going too far behind the face of the wall on either of the four corners. If the wall is too far out, use a plane to get the jamb edge closer to the wall face can be done too.
