Solve the Problem $x$ Milligrams of a Drug, Is Given By $D^{\prime}(x)=\frac{8}{x+5}$

Solve the problem.
-The second derivative of a person's body temperature, with respect to the dosage of $x$ milligrams of a drug, is given by $D^{\prime}(x) =\frac{8}{x+5}$ . One milligram raises the temperature $1.5^{\circ} \mathrm{C}$ . Find the function $D(x)$ giving the total change in temperature as a function of $x$ .

A) $\mathrm{D}(\mathrm{x}) =\ln \left|\frac{8}{\mathrm{x}+5}\right|+12.8$
B) $\mathrm{D}(\mathrm{x}) =8 \ln |\mathrm{x}+5|-12.8$
C) $D(x) =8 \ln |x+5|+1.5$
D) $\mathrm{D}(\mathrm{x}) =\ln \left|\frac{8}{\mathrm{x}+5}\right|-1.5$
