Assertion : The net magnetic force on a current loop in a uniform magnetic field is zero but torque may or may not be zero.
Reason : Torque on a current carrying coil in a magnetic field is given by `vec(tau)=nI(vec(A)Xxtau(B))`.
A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reason are true but reason is the correct explanation of assertion.
C. If assertion is true but reason is false
D. If both assertion and reason are false.
