**Conductivity and Molar Conductivity**

Conductivity is a measure of a solution's ability to conduct electricity. It depends on the concentration of ions present in the solution. Molar conductivity, on the other hand, is a measure of the conductivity of a solution per unit concentration of solute. It is calculated by dividing the conductivity of the solution by its molar concentration.

**Effect of Dilution on Conductivity and Molar Conductivity**

1. **Conductivity of a Solution Increases with Dilution (Incorrect)**

When a solution is diluted by adding more solvent, the concentration of ions in the solution decreases. As a result, the number of charge carriers responsible for conducting electricity also decreases. Therefore, the conductivity of a solution generally decreases with dilution, not increases.

2. **Molar Conductivity of a Solution Increases with Dilution (Correct)**

Molar conductivity is the ratio of conductivity to molar concentration. When a solution is diluted, the molar concentration decreases. However, the conductivity decreases at a slower rate than the molar concentration. This is because the decrease in concentration of ions is offset by the increase in the average distance between the ions, which reduces the effect of their mutual repulsion. As a result, the molar conductivity of a solution generally increases with dilution.

3. **Conductivity of a Solution Decreases with Dilution (Correct)**

As mentioned earlier, when a solution is diluted, the concentration of ions decreases. Since conductivity is directly proportional to the concentration of ions, the conductivity of a solution decreases with dilution. This is the correct statement.

4. **Molar Conductivity of a Solution Decreases with Dilution (Incorrect)**

As explained earlier, the molar conductivity of a solution increases with dilution. Therefore, this statement is incorrect.

In conclusion, the correct statements are:

b) Molar conductivity of a solution increases with dilution
c) Conductivity of a solution decreases with dilution
