Very Interesting question :
This is the experiment to know whether metals and non metals reacts with acid .
The correct option is none of these:
Explanation :
Metal + Acid ---> Salt +Hydrogen gas
Mg + 2HCl ---> MgCl2 +H2
2Al+ 6HCl---> 2AlCl3 +3H2
Test for H2 gas:
Burning matchstick produces pop sound.
Non metals + Acid ---> No reaction.
Since in all the options nonmetals are present like Charcoal which contains carbon.
Sulphur --- nonmetal
Conclusion : Only in Mg, Al test tubes pop sound is heard. So options does not match with it.
