The differential equation of the family of curves \(y=e^{x}(A \cos x+B \sin x)\) where \(A, B\) are arbitrary constants is
(A) \(\frac{d^{2} y}{d x^{2}}-9 x=13\)
(B) \(\frac{d^{2} y}{d x^{2}}-2 \frac{d y}{d x}+2 y=0\)
(C) \(\frac{d^{2} y}{d x^{2}}+3 y=4\)
(D) \(\left(\frac{d y}{d x}\right)^{2}+\frac{d y}{d x}-x y=0\)
