Explanation:

Step1: Recall conversion formula

The formula to convert Fahrenheit ($F$) to Celsius ($C$) is $C=\frac{5}{9}(F - 32)$.

Step2: Substitute the value of F

Here $F = 86$, so $C=\frac{5}{9}(86 - 32)$.

Step3: Calculate the value inside the parentheses

$86-32 = 54$.

Step4: Multiply by $\frac{5}{9}$

$C=\frac{5}{9}\times54= 30$.

Answer:

C. $30^{\circ}C$
