Match List - I with List - II :

  List - I
(Parameter)		   List - II (Unit)
(a) Cell constant (i) S cm2 mol-1
(b) Molar conductivity (ii) Dimensionless
(c) Conductivity (iii) m-1
(d) Degree of dissociation of electrolyte (iv) Ω-1 m-1
  1. (a)-(iii), (b)-(i), (c)-(iv), (d)-(ii)
  2. (a)-(iii), (b)-(i), (c)-(ii), (d)-(iv)
  3. (a)-(iii), (b)-(iv), (c)-(i), (d)-(ii)
  4. (a)-(ii), (b)-(i), (c)-(iii), (d)-(iv)

Solution

Cell constant =ℓA=m-1 

Conductivity k=1ρ=ℓRA=Ω-1 m-1 

Molar Conductivity =λm=k×1000 Molarity =S cm2 mol-1

Degree of dissociation = Number of mole dissociated out of one mole, hence, it is dimensionless.
