Multiple Choice

Solve the problem.
-In order for a chemical reaction to take place, the Fahrenheit temperature of the reagents must be at least $197.5^{\circ} \mathrm{F}$ . Find the Celsius temperatures at which the reaction may occur. $\left(\mathrm{F}=\frac{9}{5} \mathrm{C}+32\right)$

A) $\mathrm{C} \geq 91.94^{\circ}$
B) $\mathrm{C}<387.5^{\circ}$
C) $\mathrm{C} \geq 387.5^{\circ}$
D) $\mathrm{C} \leq 91.94^{\circ}$
