Central Angle of Circle Q and Circle R = 75°

Ratio of circle Q’s radius to circle R’s radius $=\frac{3}{4}$

Let $A_{1},A_{2}$ represent area of sector for circle Q and area of sector for circle R.

$\frac{A_{1}}{A_{2}}=\frac{\frac{\pi (r_{1})^2*75^{\circ}}{360^{\circ}}}{\frac{\pi (r_{2})^2*75^{\circ}}{360^{\circ}}}\\\\\frac{A_{1}}{A_{2}}=[\frac{r_{1}}{r_{2}}]^2\\\\ \frac{A_{1}}{A_{2}}=[\frac{3}{4}]^2\\\\ \frac{A_{1}}{A_{2}}=\frac{9}{16}$

Option D: 9:16
