Solution

The correct option is B $λ_{c} = λ_{\infty} - (B) \sqrt{C}$
$λ_{c} = λ_{\infty} - (B) \sqrt{C}$ (for strong electrolyte)

It is according to Debye Huckel equation for strong electrolyte.

(Relation between $λ_{c}$ and $λ_{\infty}$ is given by Debye Huckel limiting law)

Option A is correct.
