Have an idea about LENZ’s law, current induced in the pulse opposes the current that produced it(in the ckt).
Switch is cloesd, current flows, a magnetic field produced, flux cutting in the loop, its time varying magnetic field will give induced current that would be of opposite direction.
Hence you decide your optrion from 3rd and 4th.
Keep in mind about the Lenz’s law.........
