Solution

The correct option is D Assertion is incorrect but Reason is correct.
Speed of ions depend upon nature of ions and potential gradient.
Mobility of ions depends upon mass, charge and size of ions only. it is independent of the potential gradient.
Thus, assertion is incorrect but Reason is correct.
