. In the sinusoidal response of R-L-C circuit, the complementary function of the solution of i is?

A. i<sub>c</sub> = c<sub>1</sub> e<sup>(K<sub>1</sub>+K<sub>2</sub>)t</sup> + c<sub>1</sub> e<sup>(K<sub>1</sub>-K<sub>2</sub>)t</sup>
B. i<sub>c</sub> = c<sub>1</sub> e<sup>(K<sub>1</sub>-K<sub>2</sub>)t</sup> + c<sub>1</sub> e<sup>(K<sub>1</sub>-K<sub>2</sub>)t</sup>
C. i<sub>c</sub> = c<sub>1</sub> e<sup>(K<sub>1</sub>+K<sub>2</sub>)t</sup> + c<sub>1</sub> e<sup>(K<sub>2</sub>-K<sub>1</sub>)t</sup>
D. i<sub>c</sub> = c<sub>1</sub> e<sup>(K<sub>1</sub>+K<sub>2</sub>)t</sup> +c<sub>1</sub>e<sup>(K<sub>1</sub>+K<sub>2</sub>)t</sup>
Answer» B. i<sub>c</sub> = c<sub>1</sub> e<sup>(K<sub>1</sub>-K<sub>2</sub>)t</sup> + c<sub>1</sub> e<sup>(K<sub>1</sub>-K<sub>2</sub>)t</sup>
