Temperature of a person is 100° F. If its temperature increases by 3 Kelvin thentemperature of person in degree Fahrenheit isA. 103B. 104.6C. 105D. 105.4

First, we need to understand that Fahrenheit and Kelvin are two different temperature scales.

1. Convert the initial temperature from Fahrenheit to Kelvin. The formula to convert Fahrenheit to Kelvin is K = (F - 32) * 5/9 + 273.15. So, the initial temperature in Kelvin is (100 - 32) * 5/9 + 273.15 = 310.92777778 Kelvin.

2. Now, increase this temperature by 3 Kelvin. The new temperature in Kelvin is 310.92777778 + 3 = 313.92777778 Kelvin.

3. Convert this temperature back to Fahrenheit. The formula to convert Kelvin to Fahrenheit is F = (K - 273.15) * 9/5 + 32. So, the new temperature in Fahrenheit is (313.92777778 - 273.15) * 9/5 + 32 = 105.4°F.

So, the answer is D. 105.4.
