Answer & Solution

Correct Answer

(C) (III), (B) - (IV), (C) - (II), (D) - (I)

Step-by-step Solution

Detailed explanation

(A) \(\frac{d^3 y}{d x^3}=e^{\frac{d y}{d x}}\): Degree is not defined. (A) - (III) (B) \(\left(\frac{d y}{d x}\right)^2+\frac{d^3 y}{d x^3}=0\): Highest derivative is \(\frac{d^3 y}{d x^3}\). Order = 3. (B) - (IV) (C) \(\frac{d^3 y}{d x^3}+\left(\frac{d y}{d x}\right)^5=x\):…
