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).
