None of the above.  Look at the ridiculous rise of the scope over the line of the OEM iron sights.  You'll need a serious, and adjustable cheek riser in order to use such scopes.  None of the rifles pictured above have such.
 
Adjustable because if your scope ever fails for any reason, you will need to remove it and use iron sights--if your scope mount allows such--some don't.  Always have a back-up.

I use Scout mounts on all my M1s and M1As.  Scopes and other optics available with illumination, and reticular hold-overs out to 500 yds.  Dial down the magnification for very close ranges and retain zero.

I have tried almost everything available for both rifles, and despite good equipment, have found the Scout set-up ideal for me.  YMMV, but you might consider looking into such a rig.  One doesn't need any cheek riser in a well-done (as low as possible) set-up, and Scout rigs are always iron-sight friendly.

After spending a LOT of money on scope rigs for Mini-14, Garand, and M1A rifles, I have come to the firm conclusion that the Scout set-up is the best for these very similar types of rifle.  Did I mention that the Scout mount will never interfere with ejection of spent cases?  Some users of mounts for conventional scopes report such, and fairly regularly.   Basically, the mount/scope is where the designers of the rifle intended to be free space.

I had an M1D, and sold it for a tidy profit because I discovered that a Scout Mount would do what I wanted a scoped M1 to do without my taking a very collectible rifle into the field, and so likely banging it up and reducing value.  Not to mention that the offset M1D scope also required a cheek [I[offset[/I] pad, which was a PITA to remove if one was forced to revert to iron sights.

I strongly suggest you look into Scout scope mounts for your rifle.  Burris LER pistol scopes are ideal.  Just dial 'em up to 6X for 200 yds plus, and the engraved reticules correspond to 100 yd increments from there on out. Leupold QRW rings, as low as possible to suit the scope, and everything designed to keep the scope as low as possible, which is [b]critical to fast. instinctive use.

The Ultimak Scout mount replaces the front hand guard, and is as low as possible. http://ultimak.com/BuyM14.htm  Notice the repeated use of the phrase "as low as possible"?  It all begins with the rail.  After that, [I]appropriate[/I]--to YOUR scope-- Leupold QRW scope rings, which will not self-dis-assemble after removal, and which will return to zero are suggested.
