Consider the First-Order Homogeneous System of Linear Differential Equations

Consider the first-order homogeneous system of linear differential equations

What is the general solution of this system? Here, and are arbitrary real constants.

A) $\mathbf{x}(t) =C_{1} e^{-3 t}\left(\begin{array}{l}\sin (8 t) \\ \cos (8 t) \end{array}\right) +C_{2} e^{-3 t}\left[\begin{array}{l}-\cos (8 t) \\ \sin (8 t) \end{array}\right)$
B) $\mathbf{x}(t) =C_{1} e^{3 t}\left(\begin{array}{l}\sin (8 t) \\ \cos (8 t) \end{array}\right) +C_{2} e^{3 t}\left(\begin{array}{l}-\cos (8 t) \\ \sin (8 t) \end{array}\right)$
C) $\mathbf{x}(t) =C_{1} e^{-8 t}\left(\begin{array}{l}\sin (3 t) \\ \cos (3 t) \end{array}\right]+C_{2} e^{-8 t}\left(\begin{array}{l}-\cos (3 t) \\ \sin (3 t) \end{array}\right)$
D) $\mathbf{x}(t) =C_{1} e^{8 t}\left(\begin{array}{l}\sin (3 t) \\ \cos (3 t) \end{array}\right) +C_{2} e^{8 t}\left\{\begin{array}{l}-\cos (3 t) \\ \sin (3 t) \end{array}\right)$
