1) Reaction III doesn't occur.
Whereas, reaction II is possible and precipitate of PbCl2 forms.
Reaction I is possible because precipitate of BaSO4 forms.
Thus, option C is correct.
2) option B is correct as hydrogen is not alkali metal although it belongs to group 1 of the periodic table.
3) Helium is inert gas because it belongs to 18 group of periodic table and is having fully filled electronic configuration.
Moreover helium is a noble gas and noble gases are always inert.
Thus, option C is correct.
4) option B is correct as in this only oxidation takes place
As, SO32- to SO42- is oxidation because oxidation number of
sulphur goes from +4 to +6 .
Thus, option B is correct
