Unless a miracle happens and the Bears pick in the top ten then the answer is probably none of the above. The Bears aren't in a position to lose another draft pick trying to acquire a quarterback. Trubisky cost four picks, Foles cost a pick...I'm tired of it.
Same here.
At this point, we're in the middle of the first round.
I say trade down, and get some additional picks in rounds 2 and 3. The Bears can still get a guard like Tennessee's Trey Smith (6'6", 325) and a tackle like Clemson's Jackson Carman (6'5", 345) for the right side.
Add a RB like Chuba Hubbard, and a lot of the offensive problems are mitigated, especially if you can tag Allen Robinson (then, if a deal can't be worked out in time, deal him for a pick or two).
Here's a mock showing what I have in mind:
Round 1 Pick 25 (NYJ):
Trey Smith, OG, Tennessee (A)
Round 2 Pick 16:
Patrick Jones, DE/OLB, Pittsburgh (A)
Round 2 Pick 21 (L.V.):
Jackson Carman, OG/OT, Clemson (B+)
Round 3 Pick 1 (NYJ):
Chuba Hubbard, RB, Oklahoma State (A)
Round 3 Pick 15:
Tedarrell Slaton, DT, Florida (A+)
Round 3 Pick 18 (PHI):
Cade Mays, OG/OT, Tennessee (A)
Round 5 Pick 22 (T.B.):
Kellen Mond, QB, Texas A&M (A+)
Round 6 Pick 16:
Asim Rose, RB, Kentucky (A+)
Round 7 Pick 8:
Darius Stills, DT, West Virginia (A+)
Round 7 Pick 22 (T.B.):
Lorenzo Neal, DT, Purdue (A+)
Round 7 Pick 32 (T.B.):
Dyami Brown, WR, North Carolina (A+)
I get Kellen Mond, more as a #3 QB option, but he might be a decent backup if you can't get Trubisky to sign a reasonable deal to return.
Mostly, I also intend to replace the Urban/Michols duo with younger backups like Stills and Neal. Asim Rose is a backup option behind Hubabrd, especially if you move Montgomery to FB.
