Solution

The correct option is B increase in degree of ionization
We know,
$Molar conductivity = \frac{specific conductance}{concentration}$
$∴ λ_{m} = \frac{K}{C}$

$λ_{m} = \frac{K \times V o l u m e}{m o l e s}$
At dilution as volume increases, the degree of ionisation increase.
$∴$ Molar conductivity also increases.

Option B is correct.
