The Attempt at a Solution

My question is the last part "which of the following are true". I've tried these choices and all were wrong:

(1, 2, 3)
(1, 2)
(2)
(1, 3)

I really am confused. I swear 1 is right. Right? 2 seems to be right, and 3 should be wrong. But right now I'm confused and don't know what is what. Any help is much appreciated.

Yes, 1 is indeed right, and 3 should be wrong. For 2, think about which direction the current is flowing in. Use the right-hand rule to find out the direction of the magnetic for all segments of the loop.
