Hey Abhijeet

I think you meant formic acid and not "parmic acid" as option 1.

The correct option for order of conductivity is 1>3>2 (option B)

Here the compounds are acids with equal concentration.

The electrical conductivity depends upon there ions , that means, it is dependent on acidic strength

The order of acidic strength is 1>3>2

Acidic strength Increase means the increase in the degree of ionization
Thus the correct order of electrical conductivity is 1>3>2
