Solution

The correct option is A
assertion is true, reason is correct explanation for assertion.

Equivalent conductance of all electrolytes decreases with increasing concentration.
With increase in the concentration, the degree of ionization decreases and lesser number of ions are available per gram equivalent at higher concentration.
Hence, Statement-I is true, Statement-II is true; Statement-II is correct explanation for Statement-I.
