Best answer
Correct answer is (b) False

The best I can explain: Kirchhoff’s law are not applicable in the presence of a magnetic field. This is because, Kirchhoff’s law is based on the assumption that magnetic fields do not exist in closed loops. Therefore, this law cannot be used when there are time varying magnetic fields.
