Solution

The correct option is D Both Assertion and Reason are incorrect
Wherever there's a current or moving charged particle there is a magnetic field. So, it should not matter whether there is a direct current or an alternating current. The only difference in ac from dc is that in ac the magnitude of the current is continuously changing and its direction changes over a period of time. So what's changing is the rate of motion of charges but anyhow charges are in motion and hence there must be an alternating current.
