An Object Is Taken Out of A $21 ^ { \circ } \mathrm { C }$

An object is taken out of a $21 ^ { \circ } \mathrm { C }$ room and placed outside where the temperature is $4 ^ { \circ } \mathrm { C }$ room. Twenty-five minutes later the temperature is $17 ^ { \circ } \mathrm { C }$ . It cools according to Newton's Law. The temperature of the object after one hour is

A) $12.2 ^ { \circ } \mathrm { C }$
B) $12.9 ^ { \circ } \mathrm { C }$
C) $13.6 ^ { \circ } \mathrm { C }$
D) $14.3 ^ { \circ } \mathrm { C }$
E) $15.0 ^ { \circ } \mathrm { C }$
