Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
The conductivity of an electrolyte is very low as compared to a metal at room temperature because the number density of free ions in an electrolyte is much smaller as compared to number of free electrons in metals. Further, ions drift slowly due to their heavier mass.
