-The following data represent the compound yield in grams for a chemical reaction for various temperatures of the reaction. Determine the "best" model to describe the relationship between temperature and compound yield.
$\begin{array}{l|l}\text { Temperature }\left({ }^{\circ} \mathrm{C}\right) , & \text { Compound Yield (grams) , } \mathrm{y} \\\hline 50 & 4 \\60 & 12 \\70 & 14 \\80 & 21 \\90 & 26\end{array}$

A) linear model: $\mathrm { y } = - 21.7 + 0.53 \mathrm { x }$
B) exponential model: $\hat { y } = - 0.195 + 0.019 x$
C) power model: $\mathrm { y } = - 4.392 + 2.999 \mathrm { x }$
D) power model: $\hat { y } = 4.392 + 2.999 x$
