Solution

The correct option is B. $λ_{A l^{3 +}}^{\circ} + λ_{S O_{4}^{2 -}}^{\circ}$
$A l_{2} {(S O_{4})}_{3} ⟶ 2 A l^{3 +} + 3 S O_{4}^{2 -}$
"Kohlrausch's law states that the equivalent conductivity of an electrolyte at infinite dilution is equal to the sum of the conductances of the anions and cations."
$λ_{A l_{2} {(S O_{4})}_{3}}^{o} = 2 λ_{A l^{3 +}}^{o} + 3 λ_{S O_{4}^{2 -}}^{o}$
Since equivalent conductance are given only for cation and anion, the equivalent conductance at infinite dilution is: $λ_{A l^{3 +}}^{\circ} + λ_{S O_{4}^{2 -}}^{\circ}$
