Multiple Choice

Solve the problem.
-In order for a chemical reaction to take place, the Fahrenheit temperature of the reagents must be at least $166.17 ^ { \circ } \mathrm { F }$ . Find the Celsius temperatures at which the reaction may occur. $\left( \mathrm { F } = \frac { 9 } { 5 } \mathrm { C } + 32 \right)$

A) $C \geq 74.54 ^ { \circ }$
B) $C \geq 331.11 ^ { \circ }$
C) $C < 331.11 ^ { \circ }$
D) $C \leq 74.54 ^ { \circ }$
