A
If both assertion and reason are true and reason is the correct explanation of assertion
50%
B
If both assertion and reason are true but reason is not the correct explanation of assertion
20%
C
If assertion is true but reason is false
15%
D
If both assertion and reason are false
14%
Solution:
Conductivity always decreases with the decrease in concentration both, for weak and strong electrolytes. This can be explained by the fact that the number of ions per unit volume that carry the current in a solution decreases on dilution.
