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

Answer

To analyze the statements provided, we will break down the reasoning step by step.

### Step 1: Understanding Volatility
- **Definition of Volatility**: Volatility refers to the tendency of a substance to vaporize. A more volatile liquid will evaporate more readily than a less volatile one.
- **Implication**: If we have two volatile liquids, one will be more volatile than the other, meaning it will have a higher tendency to form vapor.

**Hint**: Remember that volatility is linked to how easily a liquid can turn into vapor.

### Step 2: Examining Statement-1
- **Statement-1**: "On evaporation of a solution of two volatile liquids, vapor will always be rich in the more volatile component."
- **Reasoning**: When a solution containing two volatile liquids (let's say A and B) is evaporated, the component that is more volatile (A) will produce more vapor than the less volatile component (B). Therefore, the vapor phase will contain a higher concentration of the more volatile component.

**Hint**: Think about which liquid would escape into the vapor phase more readily.

### Step 3: Examining Statement-2
- **Statement-2**: "More volatile component has the lowest boiling point."
- **Reasoning**: The boiling point of a liquid is the temperature at which its vapor pressure equals the atmospheric pressure. A more volatile liquid will reach this vapor pressure at a lower temperature compared to a less volatile liquid. Hence, the more volatile component indeed has a lower boiling point.

**Hint**: Consider how boiling points relate to vapor pressures and temperature.

### Step 4: Conclusion
- Both statements are correct based on the definitions and principles of volatility and boiling points.
- Therefore, we can conclude that both Statement-1 and Statement-2 are true.

**Final Answer**: Both Statement-1 and Statement-2 are correct.
