If $$\frac{\cosec^2 \theta}{\cosec^2 \theta - \cot^2 \theta} = \frac{13}{4}, 0^\circ < \theta < 90^\circ$$, then the value of $$\frac{52 \cos^2 \theta - 9 \tan^2 \theta}{18 \sec^2 \theta + 8 \cot^2 \theta}$$ will be:

A

$$\frac{4}{11}$$

B

$$\frac{8}{11}$$

C

$$\frac{8}{13}$$

D

$$\frac{5}{11}$$
