I disagree.

who = subject form
whom = object form

Please re-think.
is it # 3
No. You're just guessing.

In 1, "Who" should be "Whom" because it's the direct object of the verb "would choose" -- you would choose whom...

In 3, "Whom" should be "Who" because it's the subject of the sentence (main verb is "made").

No more guessing. Think.
