The Figure Shows the Orientation of a Rectangular Loop Consisting $\theta$

The figure shows the orientation of a rectangular loop consisting of 80 closely wrapped turns each carrying a current I.The magnetic field in the region is () mT.The loop can turn about the y axis.If $\theta$ = 30 $\degree$ , a = 0.40 m, b = 0.30 m, and I = 8.0 A, what is the magnitude of the torque exerted on the loop?

A) 2.5 N . m
B) 1.5 N . m
C) 3.1 N .m
D) 2.7 N . m
E) 0.34 N. m
