Answer:-

H2SO3 (aq)

Explanation:-

NaCl, KOH and HCl ionic compounds.

Ionic compounds dissociate into ions in water.

Ions can carry electricity in water. So NaCl, KOH and HCl are all strong electrolytes.

H2SO3 is not a strong acid and dissociates to a small extent into ions in water.

Hence number of ions formed is less. Hence it is a weak electrolyte.
