But some of my friends saying H2S is ionic and conduct in aqueous state because of free ions of H+ and S2- plus Mg is not extracted by coke?
Covalent + non conductor. And Mg extracted by electrolysis as above zinc in reactiviry series.

Oh ok...I must have remembered wrong then:(...I marked the slag one but while rechecking my mind started sprouting random doubts so I changed it to iron...
Iron was solid in the option whereas it is molten in reality.
