Consider the integral

$$\oint _{c}\frac{sin\left ( x \right )}{x^{2}\left ( x^{2}+4 \right )}dx$$

where $C$ is a counter-clockwise oriented circle defined as $\left | x-i \right |=2$. The value of the integral is

  1. $-\frac{\pi }{8}\sin\left ( 2i \right )$
  2. $\frac{\pi }{8}\sin\left ( 2i \right )$
  3. $-\frac{\pi }{4}\sin\left ( 2i \right )$
  4. $\frac{\pi }{4}\sin\left ( 2i \right )$
