The range of clinical thermometer is between:
A. ${35^0}C{\text{ and 5}}{{\text{2}}^0}C$.
B. ${25^0}C{\text{ and 3}}{{\text{2}}^0}C$.
C. ${65^0}C{\text{ and 7}}{{\text{2}}^0}C$.
D. ${35^0}C{\text{ and 4}}{{\text{2}}^0}C$.

- Hint: In this question, first we have to know what is a thermometer and what is it’s unit of measurement and how to measure a temperature in a thermometer.

Complete step-by-step solution -

Thermometer: An instrument for measuring and indicating temperature, typically one consisting of a narrow, hermetically sealed glass tube marked with graduations and having at one end a bulb containing mercury or alcohol which extends along the tube as it expands.
The thermometer used for measuring the temperature of the human body is called a clinical thermometer.
The range of a clinical thermometer is from ${35^0}C{\text{ and 4}}{{\text{2}}^0}C$.
Hence, the correct answer is option (D).

Note: In this type of questions, first we should have some knowledge about the device that is mentioned in the question. Then we have to find out its use and its types. By finding out all these things, we can also find the range of measurement of that device. Through this we will get the answer.
