Solution

The correct option is C Assertion is correct but Reason is incorrect
Yes, the assertion is correct but the current carried by a ion depends upon its mobility and mobility of ion changes with change in size of ions;
cation is having smaller size than anion and moves with greater speed and hence carry large current;
hence, the current carried by cation and anion is different.
