The number of correct statements from the following is $\displaystyle \_\_\_\_$
(A)
Conductivity always decreases with decrease in concentration for both strong and weak electrolytes.
(B)
The number of ions per unit volume that carry current in a solution increases on dilution.
(C)
Molar conductivity increases with decrease in concentration.
(D)
The variation in molar conductivity is different for strong and weak electrolytes.
(E)
For weak electrolytes, the change in molar conductivity with dilution is due to decrease in degree of dissociation.
