Statement-1: It is better to wash the clothes in cold soap solution.
Statement-2: The surface tension of cold solution is more than the surface tension of hot solution:

Options

A. Statement-1, is true, Statement-2 is true, Statement-2 is correct explanation for statement-1
B. Statement-1 is true, statement-2 is true, statement-2 is NOT a correct explantion 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 given in the question, we will break down the concepts of surface tension, soap solutions, and their effects on washing clothes.

### Step-by-Step Solution:

1. **Understanding Surface Tension**:
- Surface tension is a property of liquids that causes them to behave as if their surface is covered with a stretched elastic membrane. It is influenced by the temperature of the liquid and the presence of surfactants (like soap).

2. **Effect of Soap on Surface Tension**:
- When soap is added to water, it reduces the surface tension of the water. This reduction in surface tension allows the water to spread more easily and penetrate fabrics, which helps in removing dirt and stains from clothes.

3. **Temperature and Surface Tension**:
- Generally, as the temperature of a liquid increases, its surface tension decreases. This means that hot soap solutions will have lower surface tension compared to cold soap solutions.

4. **Analyzing Statement-1**:
- Statement-1 claims that it is better to wash clothes in a cold soap solution. However, since hot soap solutions have lower surface tension, they are more effective for washing clothes. Therefore, this statement is **false**.

5. **Analyzing Statement-2**:
- Statement-2 states that the surface tension of cold soap solution is more than that of hot soap solution. This is true because, as established, heating the soap solution reduces its surface tension. Thus, this statement is **true**.

6. **Conclusion**:
- Since Statement-1 is false and Statement-2 is true, the correct answer is that Statement-1 is incorrect while Statement-2 is correct.

### Final Answer:
- Statement-1 is false, and Statement-2 is true.
