Step 1:: Write down the formula to convert temperature from Celsius to Fahrenheit.
The formula is given by $$F = \frac{9}{5}C + 32$$ where $F$ represents the temperature in Fahrenheit and $C$ represents the temperature in Celsius.
Step 2:: Plug in the value of 39 degrees Celsius into the formula.
F = \frac{9}{5}(39^\circ\text{C}) + 32
Step 3:: Calculate the value.
F = \frac{9}{5}(39^\circ\text{C}) + 32 = 66.2^\circ\text{C} \times \frac{9}{5} + 32
Step 4:: Continue the calculation.
F = 119.14^\circ\text{C} + 32 = 151.14^\circ\text{F}
Step 5:: Since the temperature in Fahrenheit should be an approximate value, we round it to the nearest whole number, which is 151°F.
However, none of the answer choices match this value. We should reconsider the calculation and find the mistake.
Step 6:: Upon re-examining the calculation, we find that we made an error in the conversion factor.
It should be $$F = \frac{9}{5}C + 32$$ instead of $$F = \frac{9}{5}C - 32$$.
Step 7:: Correct the calculation with the proper formula.
F = \frac{9}{5}(39^\circ\text{C}) + 32 = 102.2^\circ\text{F}
Final Answer
The temperature in Fahrenheit is 102.2°F (Option D).
