B. b. Statement-1 is true, statement-2 is true, statement-2 is not a correct explanation for statement-1
C. c. mStatement-1 is true, statement-2 is false
D. d. Statement-1 is false, statement-2 is true

Answer

To analyze the statements regarding clinical thermometers, we will break down the reasoning step by step.

### Step 1: Understanding Statement 1
**Statement 1:** Clinical thermometers are made long and thin.

- Clinical thermometers are designed to measure body temperature accurately. The design of being long and thin serves a specific purpose.
- A long and thin thermometer increases the surface area in contact with the heat source (the body), which allows for better heat transfer. This is crucial because the temperature difference between the human body and the surrounding environment is relatively small.

### Step 2: Understanding Statement 2
**Statement 2:** Long and thin thermometers can easily be kept in the mouth below the tongue.

- The design of clinical thermometers being long and thin also facilitates their use. They can be easily placed under the tongue, which is a common method for measuring body temperature.
- This statement highlights a practical aspect of the thermometer's design, making it user-friendly and convenient for clinical use.

### Step 3: Evaluating the Relationship Between the Two Statements
- Both statements are true. The first statement explains the primary reason for the design of clinical thermometers, which is to enhance heat transfer due to increased surface area.
- The second statement provides a secondary reason, which is the practicality of using the thermometer by placing it under the tongue.

### Conclusion
- Therefore, both statements are true, but the second statement does not serve as a correct explanation for the first statement. The first statement's explanation is based on the physics of heat transfer, while the second statement focuses on usability.

### Final Answer:
- Statement 1 is true.
- Statement 2 is true but not a correct explanation of Statement 1.
