JEE Math Practice Question

Let $$ I=\int_{\pi / 4}^{\pi / 3}\left(\frac{8 \sin x-\sin 2 x}{x}\right) d x $$. Then

1. A.$${\pi \over 2} < I < {{3\pi } \over 4}$$
2. B.$${\pi \over 5} < I < {{5\pi } \over {12}}$$
3. C.$${{5\pi } \over {12}} < I < {{\sqrt 2 } \over 3}\pi $$
4. D.$${{3\pi } \over 4} < I < \pi $$
