Question

Figure (a–d) shows the readings on four different thermometers. Indicate which of the reading shows the normal human body temperature?

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

The explanation for the correct option

In case of option ( c )

Normal human body temperature:

1. $98.6°F(37°C)$ is average normal body temperature.
2. The normal body temperature can be within a wide range, from $97°F(36.1°C)$ to $99°F(37.2°C)$.
3. Normal body temperature also depends upon age.
4. In the case of babies and children, the average body temperature varies from $97.9°F(36.6°C)$ to $99°F(37.2°C)$.
5. In the case of adults, the average body temperature varies from $97°F(36.1°C)$ to $99°F(37.2°C)$.
6. In the case of senior citizens, the average body temperature is lower than $98.6°F(37°C)$.

According to the given figure, the temperature is $37°C$. Even if the reading is of a baby, adult, or senior citizen. The value lies in a normal body temperature range.

The explanation for the incorrect option

In case of option ( a )

According to the given figure, the temperature is $38.5°C$. Even if the reading is of a baby, adult, or senior citizen. The value doesn't lie in a normal body temperature range. The value is greater than the excepted normal range.

In case of option ( b )

According to the given figure, the temperature is $36°C$. Even if the reading is of a baby, adult, or senior citizen. The value doesn't lie in a normal body temperature range. The value is less than the excepted normal range.

In case of option ( d )

According to the given figure, the temperature is $39.6°C$. Even if the reading is of a baby, adult, or senior citizen. The value doesn't lie in a normal body temperature range. The value is greater than the excepted normal range.

Hence, option ( c ) is the correct option.
