A current loop in a magnetic field:
a)
can be in equilibrium in two orientations, one stable while the other is unstable.
b)
experiences a torque whether the field is uniform or nonuniform in all orientations.
c)
can be in equilibrium in one orientation.
d)
can be in equilibrium in two orientations, both the equilibrium states are unstable.
A current loop is a magnetic field is in equilibrium in two orientations one is stable and another unstable.
Do not experience a torque in some orientations.
