Answer

Explanation:

Step1: Recall conversion formula

The conversion formula from Celsius ($C$) to Fahrenheit ($F$) is $F=\frac{9}{5}C + 32$. We want to find when $F = C$.

Step2: Substitute and solve

Substitute $F = C$ into the formula: $C=\frac{9}{5}C+32$. First, move the $C$ - terms to one side: $C-\frac{9}{5}C=32$. Combine like - terms: $\frac{5C - 9C}{5}=32$, so $-\frac{4C}{5}=32$. Multiply both sides by $-\frac{5}{4}$: $C = 32\times(-\frac{5}{4})=-40$.

Answer:

A. -40 degrees
