Didn't you just ask this at http://openstudy.com/study#/updates/518e59bce4b0cf6dd8f43936 ? Anyways, explain WHY you chose A, and perhaps someone will help you.

Actaully I did what you said and I redid the problem and I think the answer is F but when I did it I didn;t have the e^2x on the outside so that is confusing me a little

$$\text{use the product rule} \huge (f*g)'=\color{green}{f'}g+f \color{red}{g'}$$
$$\huge f=e^{2x},g=\cos(3x)$$
$$\huge \color{green}{f'=2e^{2x}}, \color{red}{g'=- 3 \sin(3x)}$$
