Induced Torque on a Triangular Loop

A triangular conducting loop with vertices at (0,0), (L,0), and (0,L) is positioned in the xy-plane. A uniform magnetic field $B$, directed in the $+z$ direction, is confined to the first quadrant ($x>0, y>0$). If the magnitude of the magnetic field increases at a rate of $dB/dt$, which of the following describes the resulting rotational motion of the loop?
