Multiple Choice

Solve the problem.
-In order for a chemical reaction to remain stable, its Celsius temperature must be no more than $121.93 ^ { \circ } \mathrm { C }$ . Find the Fahrenheit temperatures at which the reaction will remain stable. $\left( F = \frac { 9 } { 5 } C + 32 \right)$

A) $\mathrm { F } \leq 251.47 ^ { \circ }$
B) $F \geq 49.96 ^ { \circ }$
C) $\mathrm { F } \geq 251.47 ^ { \circ }$
D) $\mathrm { F } \leq 49.96 ^ { \circ }$
