Consider the statements S1 and S2:
S1: Conductivity always increases with decrease in the concentration of electrolyte.
S2: Molar conductivity always increases with decrease in the concentration of electrolyte.
The correct option among the following is:

Options

A. Both S1 and S2 are wrong
B. S1 is correct and S2 is wrong
C. S1 is wrong and S2 is correct
D. Both S1 and S2 are correct

Explanation

To solve the question regarding the statements S1 and S2, we will analyze each statement individually and determine their correctness based on the principles of electrochemistry.

### Step 1: Analyze Statement S1
**Statement S1:** "Conductivity always increases with decrease in the concentration of electrolyte."

- **Understanding Conductivity:** Conductivity (κ) is a measure of how well a solution can conduct electricity, which depends on the number of ions present in the solution.
- **Relation to Concentration:** As the concentration of an electrolyte increases, the number of ions in the solution increases, leading to higher conductivity. Conversely, if the concentration decreases, the number of ions decreases, leading to lower conductivity.
