Please help.

[12]36. A piece of wire is bent in the shape shown (two 156 cm straight sections and a 3/4 of a circle section with radius r = 120 cm). Based on this information i = 17.4 mA which of the following is TRUE? Note that point P is the center of the 3/4th circular section. The current in the wire is 17.4mA. Give your answer using the format "s", y. -.." Statements: (a) The magnetic field at point P is due only to the current in the two straight sections. i (b) The magnetic field at point P is due only to the current in the 3/4 circle section. (c) The magnetic field at P is exactly zero. (d) The magnetic field at P is can be easily determined if we use the law of Biot and Savart. (e) The law of Biot and Savart would not work for this problem. It would be better to use Amperes Law. (f) The magnetic field at point P is due to the combination of the full current in the vertical straight section and half the current in the 3/4 circle
