Solution

The correct options are
B Air
C Rubber
D H2O
To be a good electric conductor, a material needs to have free electrons or ions.
Sulphuric acid has H+ and SO4 ions.
H2O is pure water which does not have any salts and is a bad conductor of electricity.
Air and rubber are also bad conductors as they have no free electrons or ions.
