A scientist is studying the relationship of two quantities S

and T

in an experiment. The scientist finds that under certain conditions, as the quantity of S

increases, the quantity of T

decreases. After taking measurements, the scientist determines that the rate of change of the quantity of S

with respect to the quantity of T

present is inversely proportional to the natural logarithm of the quantity of T

. Which of the following is a differential equation that could describe this relationship?
