Which of the following differential equations has the same order and degree
(a) \( \frac{d^{4} y}{d x^{4}}+8\left(\frac{d y}{d x}\right)^{6}+5 y=e^{x} \)
(b) \( 5\left(\frac{d^{3} y}{d x^{3}}\right)^{4}+8\left(1+\frac{d y}{d x}\right)^{2}+5 y=x^{8} \)
(c) \( \left[1+\left(\frac{d y}{d x}\right)^{3}\right]^{2 / 3}=4 \frac{d^{3} y}{d x^{3}} \)
(d) \( y=x^{2} \frac{d y}{d x}+\sqrt{1+\left(\frac{d y}{d x}\right)^{2}} \)
