B. Statement-1 is True, Statement-2 is True, Statement-2 is NOT a correct explanation for Statement-8
C. Statement-1 is True, Statement-2 is False
D. Statement-1 is False, Statement-2 is True

Answer

To analyze the statements given in the question, we will break down the concepts of molarity and molality, and then evaluate the truth of each statement.

### Step-by-Step Solution:

1. **Understanding Molarity (M)**:
- Molarity is defined as the number of moles of solute per liter of solution.
- A 1 M (one molar) solution contains 1 mole of solute dissolved in enough solvent to make a total volume of 1 liter of solution.

2. **Understanding Molality (m)**:
- Molality is defined as the number of moles of solute per kilogram of solvent.
- A 1 m (one molal) solution contains 1 mole of solute dissolved in 1 kilogram of solvent.

3. **Comparing Concentrations**:
- In a 1 M solution, since the total volume is 1 liter, the mass of the solvent must be less than 1000 grams (1 kg) because the solute also contributes to the total volume of the solution.
- In a 1 m solution, the mass of the solvent is exactly 1000 grams (1 kg), and the solute does not contribute to the mass of the solvent.

4. **Conclusion for Statement 1**:
- Since a 1 M solution has less than 1000 grams of solvent and contains 1 mole of solute, it is more concentrated than a 1 m solution, which has 1 kg of solvent and also contains 1 mole of solute.
- Therefore, **Statement 1 is true**: A one molar solution is always more concentrated than a one molal solution.

5. **Conclusion for Statement 2**:
- The amount of solvent in a 1 M solution is less than 1000 grams, while in a 1 m solution, it is exactly 1000 grams.
- Thus, **Statement 2 is also true**: The amount of solvent in a 1 M and a 1 m aqueous solution is not equal.

### Final Evaluation:
Both statements are correct. Therefore, the conclusion is that both Statement 1 and Statement 2 are true.
