Solution
The correct option is A (ii), (iii) and (iv) only
Most of the gases are covalent compounds.
HCl do not releases proton (H+) in the absence of water this indicates that the ionization of HCl is not possible in the absence of water. So it has covalent nature.
Dry HCl doesn't conduct electricity because of its non-ionic nature or Covalent nature.
Most of the active metal reacts with HCl to form respective Metal chloride and Hydrogen gas. However, it doesn't indicate the nature of the bond of HCl in aq solution because they are already in ionic form.
Ex- Mg(s)+HCl(aq)→MgCl2(aq)+H2(g)
Hence option A is correct
